SNTP and NTP protocols enable your program to get the exact time from public time servers over the Internet.
Keep all computers in your multi-tier application synchronized with
atomic clock to get rid of problems with different local time.
Why Rebex Time
Get the exact time from an atomic clock
Time for .NET is a powerful and easy-to-use component for C#, VB.NET
and other .NET languages. It implements the client side of SNTP, NTP, TIME and DAYTIME
protocols that enable your .NET applications to get exact time from public time
servers over the Internet. This makes it easy to keep all the computers running
your application synchronized with an atomic clock to eliminate problems
caused by mismatched system time, or to get the exact time value for your
time-critical database entries. Determining the right time has never been easier.
Synchronize with a time server in a single line of code
It is easy getting started with Rebex Time for .NET.
The most common operation - synchronizing the local system time with
a time server - only takes a single line of code.
Advanced SNTP and NTP functionality
Rebex Time for .NET supports SNTP and NTP versions 3 and 4.
With few lines of code, you can determine the time difference between the local system
and remote time server, set the local system clock to a desired value, determine
the time server stratum or access additional NTP packet fields.
