AtomTime 98
All PCs suffer from a curse - they cannot keep time. Believe it or not, a five year old can keep time better than most home computer systems. In fact, left alone the clock on your computer will slowly drift until, after a few months, the time will be off by several minutes. In a year, it could be off by an hour or more!
Keeping the clock
up-to-date and reasonably accurate can be a royal pain, unless you use a
product such as AtomTime98.
This is a simple little product, whose only purpose is to occasionally get the current time from a time server (a system which keeps perfectly accurate time) and set your clock correctly.
The product is only $10 - which, for me, was a small price to pay to not have to ever deal with an inaccurate clock again. AtomTime98 was trivial to install and requires almost no maintenance. It runs in the system tray, where the program occasionally gets the time and makes any corrections that are necessary.
A very useful product. Highly recommended, if keeping an accurate time is important to you.
