Free sntp software for windows

TTimeServ is an updated version of Nathan Andersons time server component adding SNTP support.
TWSTimeClient is an updated version of Chris Barbers time client component adding SNTP support and functions to change the PC UTC time.
SNTP is a tool that provides time correction with fractional seconds, unlike the earlier Time protocol that is round seconds only.

Synchronizes your PC clock to the world standard. An SNTP client that is a whole lot more. SetTime Client also includes a stop-watch timer and complete scheduling features. SetTime Client can display a message, check the time, run a program, or open a document at anytime - any day. Get on time. Stay on time. Be on time.

NetTime is a free and simple time synchronization client for Win32, providing a server and client for RFC868 and SNTP. Its main claim to fame is that it is small, simple and unobtrusive.
Time Servers:
This is a list of servers with which NetTime will synchronize. Each synchronization contacts all the specified servers, so adding servers to the list increases network traffic. Once all servers have been contacted, some number of time values are available.
The number of time values may be less than the number of servers if some of the servers are unreachable. Once all available time values are retrieved, they are used as follows:
- If no values are retrieved, nothing happens.
- If one value is retrieved, the local PCs clock is set to this time.
- If two values are retrieved, the local PCs clock is set to the average of the two values.
- If three or more values are retrieved, the local PCs clock is set to the average of all the values that agree with each other. This allows NetTime to synchronize the clock correctly even if a minority of servers are sending bogus times.
Update Interval:
This is the basic frequency with which NetTime will synchronize the local PCs clock with the time server(s). For example, if this is set to 120, NetTime will synchronize every two minutes.
This might be an appropriate setting when the server is on a local LAN. For servers you are connecting to through the Internet, a higher value would be appropriate to reduce traffic and load on the public servers.
Retry Interval:
This is the frequency with which NetTime makes additional attempts once time synchronization has failed. Do not set this too low if you have a dialup Internet connection, as NetTime will continue to make attempts while your connection is down.
Max Free Run:
This determines how long the local PCs clock is allowed to run unsynchronized before it is considered to have become untrustworthy. When this interval has elapsed since the most recent successful synchronization, NetTime considers itself unsynchronized, draws a red "X" across the desktop icon, and ceases supplying the time to clients.
Warn if Adj Greater:
This determines how large an adjustment NetTime is permitted to make to the local PCs clock before it must warn the user. If NetTime is running as a service and has no connection to the user (for example, when Windows is logged out), it always adjusts the time.
Check "Never Warn" if you want the local clock to be updated no matter what. NetTime makes no special provision for daylight savings time, so if you have warnings enabled and an interval of less than one hour, you will be warned when the time change occurs.
Allow other computers to sync to this computer:
Checking this box causes NetTime to run a server thread that can be synchronized to by other computers running NetTime or compatible software.
If you are installing NetTime on a LAN, the preferred setup is to have one or two computers synchronized to external, authoritative sources, and use these as local servers for the rest of the network.

Sam Spade is a free and useful network query utility.
Main features:
- Each tool displays its output in its own window, and everything is multi-threaded so you dont need to wait for one query to complete before starting the next one
- Some functions are threaded still further to allow lazy reverse DNS lookups (never do a traceroute -n again)
- The output from each query is hotlinked, so you can right click on an email address, IP address, hostname or internic tag to run another query on it
- Appending the results of a query to the log window is a single button function
- Theres a lot of online help, in both WinHelp and HTMLHelp formats. This includes tutorials, background information and links to online resources as well as the program manual itself
ping
ping a network host to see if its alive, and to see how long it takes packets to get there and back
nslookup
Find the IP address from a hostname, or vice-versa
whois
Ask a whois server who owns a domain name. Sam Spade will usually ask the right whois server automatically, or you can query a particular server. Whois queries for .com/.net/.org addresses are directed to the correct registrar automatically.
IP block whois
Ask a whois server who owns a block of IP addresses
dig
A more advanced DNS query tool. Dig asks a DNS server for all the information it has about a host
traceroute
Find the route packets take between you and a remote system. Both a slow, step-by-step mode and a fast parallel query mode are available.
finger
Lookup user information on a remote unix system
SMTP VRFY
Ask a mail-server whether an email address is real and whether its being forwarded to other addresses. Also attempt partial delivery to a range of addresses to discover whether a given address is valid or not.
web browser
Browse the web, viewing the raw HTTP traffic rather than the rendered HTML. This lets you see the http headers and the raw HTML. Very handy for debugging CGI scripts.
It will not send any identifying information to the webserver, and by not supporting file download, java, javascript, cookies or anything else it has far fewer security holes than real browsers. As it doesnt render the HTML it makes attempts to hide information (such as hidden form fields, white-on-white text, meta fields etc.) obvious. These make it a useful tool for investigating malign websites
keep-alive
Sends http packets to your ISPs webserver every minute or so, to keep a dialup link active
DNS zone transfer
This asks a DNS server for all the information it has about a domain. It automatically finds the authoritative servers for a domain and will query one or all of them.
SMTP relay check
This checks whether a mailserver is secure. It attempts to send email back to yourself via somebody elses email server (one which youre not supposed to have access to). Hopefully itll fail, but if it doesnt the mailserver is open to all sorts of abuse and the administrator needs to secure it
Usenet cancel check
This asks your local news-server to look for cancelled messages in a set of groups
website download
This will copy a website to disk.
website search
This searches a website for anything matching a list of patterns
email header analysis
This will check the Received lines in an email header for consistency. It can help in tracking down the true source of forged email
Blacklist lookups
This will check the Realtime Blackhole List, Dialup User List and Relayed Spam Source List to see if any of a hosts addresses are listed
abuse.net query
This will identify the email address responsible for abuse issues at a given domain using the database maintained by abuse.net
S-Lang scripting
Many features can be configured and scripted using the embedded S-Lang scripting language.
Time
Query a remote host to see what time it thinks it is, via a range of protocols including SNTP. Optionally set the local systems time via SNTP at each application startup.
Enhancements:
- S-Lang scripting
- Programmable hotkeys
- Configurable foreground text colour and font
- Support for frames when crawling a website
- Tab selection between subwindows
- whois.crsnic.net redirection to handle new TLD registrars
- Updated HTMLHelp documentation
- Bugfixes. Lots of bugfixes.
- Configurable background pattern or colour
- Set local system time from SNTP server
- Better email header parsing
- Complaint letter composition
- Toolbars split, so they can be placed independently
- (Optional) flat IE4/5 style toolbars
- Increase / decrease font size temporarily

Atomic Clock NTP Time Client allows a client to synchronise time to a selected NTP server TimeTools SNTP Client Software is a freeware program that runs on any Windows workstation and server. This software will allow a certain client to synchronise time to a selected NTP server.
The utility periodically polls the specified ntp server at periodic intervals specified by the user and optionally synchronises time to the server.
TimeTools SNTP client software and the Windows Time Synchronisation service (Windows Time) cannot co-exist on the same system, since they both attemp to use UDP port 123 (NTP). You can disable the Windows Time service from the service manager to avoid this problem and rely on the NTP server monitor to synchronise time.
Main features:
- Operates with unicast or broadcast NTP or SNTP
- Full audit log
- Ensures system time of client closely tracks that of an NTP server.
- Windows 32 bit service.
