Welcome to Weather-Above
Windows real time clock monitoring and synchronization utility
ClockMon™©
To monitor the clock drift we are using a utility called ClockMon ,in the settings we have check the clocks every 30 minutes
the information is written to a log file no other settings are active as we are only monitoring and logging the clock drift
info from ClockMon™© website
An "**" following the calculated difference between the two times indicates the system clock was reset for that log entry. If the "**" is not present, then the system clock was not reset for that sample. An "!!" indicates that ClockMon™ discovered an unusual occurrence: that the system clock was found to be ahead of the RTC time rather than behind it as normally expected (i.e. that the Windows system clock appears to be running faster than the Real Time Clock rather than slower as is normally expected). As far as I know, this is only an issue on Windows NT/2K/XP systems and not on Win9x/Me systems.
