Back in the 80s, the "Simple Network Time Protocol" (SNTP) was established to do just that.
The best utility I've seen (for Windows machines) is "D4TIME" ("Daemon for time") which is freeware. Do a search and you should be able to find it. I have it on my machines here. It gives a list of the hundreds of SNTP servers available on the net. I use time.nist.gov which is run by the National Standards Institute in Boulder, CO. The protocol is useful in that it adjusts for the "lag" between machines as well, so the time stays pretty uniformly accurate. I have it update about every five minutes; it is no more complicated than a "ping."
FWIW, I also have a daemon that runs on my Linux box for the same reason. Since each of the machines on my network syncs with the same SNTP server, the time on each computer is the same to within a few microseconds.
