Freeware to Sync and Hear Your Computer's Clock

WorldTimeServer.com says that its freeware "Atomic Clock Sync" utility can help you keep your local computer up-to-date with the exact current time. The program will reference an atomic clock server to get the current time, and can be set to automatically check the time once a day.

If that's still not enough to keep you on schedule, Lux-Aeterna's "Multilingual Speaking Clock" is a freeware program that turns your computer into a speaking clock, capable of telling you the time on over 25 different languages. According to their website, you can set it to automatically announce the time in regular intervals. The clock also features an alarm that can be set to remind you of important events with any sound file.
