I have noticed that the system clock in all pc''s are not accurate,
They are close but almost all pc's and notebooks gain/lose many seconds per week.
The timefade is worst in those PC's which are used the most and/or rebooted the most. I haven't tested hibernated/standby but I suspect that could affect time gain/loss as well.
There are many freeware utilities that can sync your system time to the atomic clocks. To get a list do a google seach on set time sntp freeware
Ideally I would like inetprot to make sure that my system time is accurate.
It already blocks changes to system time from users but but it should then go one step further and do a sntp query and ensure that the system clock is accurate.
This would protect the PC from both "normal" system time fade as well as overt attempts by the user to change the PC clock. Today - without this function - my pc's system time is or will become a few minutes off and unless the inetprot administrator takes to time to manually fix it, the time will simply be inaccurate and continue to fade even more inaccurate.
An alternative to inetprot providing this above function would be to have Inetprot continue to block changes by user to system time but allow a 3rd party utility to set to the atomic clock. this is less ideal than having the function intergrated into inetprot but I guess it would work ok.
