We have several questions regarding the relationship between linux system time vs. TSC vs. RTC. Our observations based on the attached script are as follows: It seems that linux system time is completely independent from TSC time. Are TSC clock values used to calculate the system time? The R…

system time( date command) is rtc time. but date application may not go to HW to get the time from RTC. It has its own userspace way of maintaining the time. TSC is a free running timer which stat during boot , 7 seconds before kernel boot. that offset will always remain. To use TSC you should use…

After running for a couple of days here is a more precise factor:
31.24851168 Mhz
Is this expected?

TSC Controlled Signals
