Older computers may not have a BIOS that is compatible with any year 2000 dates.If your computer was manufactured before 1995, we recommended that you contact the manufacturer to determine if the motherboard's BIOS is Y2K compatible.The Windows clock, as you know, is at the bottom right of your desktop and pops up time and date information when you click on it. To change the current server, click on “Change settings” button.
If the date has reset to the BIOS manufacturer date, epoch, or a default date such as 1970, 1980, or 1990 it is a good indication that the CMOS battery is failing or is already bad.
That is by far the simplest approach to guaranteeing the Mac consistently shows the proper time in the clock and uses the proper date and time with applications.
This is the recommended approach, particularly for Mac users who travel or who leave their computers off for an extended period of time, as the latest region and time is pulled automatically from Apple servers to set the proper clock and date information.
Time synchronization is critical for the proper operation of many Windows services and line-of-business applications.
The Windows Time service uses the Network Time Protocol (NTP) to synchronize computer clocks on the network so that an accurate clock value, or time stamp, can be assigned to network validation and resource access requests.
The service integrates NTP and time providers, making it a reliable and scalable time service for enterprise administrators.” The MS site was last updated in February and didn’t refer to Monday’s issues.
