It is important that the time clock within your computer is kept at the correct time. Many of the functions are time sensitive and an incorrect System Time can cause problems for which the solution is not at first obvious.
Computer clocks are not always accurate. The change to and from British Summer Time must be reflected in your computer's time for your software to run efficiently. The Date must also be correct.
The Date/Time can be found in
Windows 3.x Main, Control Panel, Date/Time
Windows 95 Start, Settings, Control Panel, Date/Time
