Linux System Time Drift at Tamara Bye blog

Linux System Time Drift. For proper ntp support, as defined by the rfc, a client must be able to merge time from multiple servers, compensate for delay, and keep track of. Something is likely resetting your system date to some external time source that maybe only has 1 second resolution. Chrony can synchronize a system clock with ntp. If your system is not kept running all of the time, running ntpdate at boot time seems like a good option. In the short term, changing the clock source to 'hpet' (temporarily via echo hpet > /sys/devices/system/clocksource/clocksource0/current_clocksource,. Set the hardware clock to a specified time; Display the hardware clock time; Warning some software can freak if the computers time goes backwards. The driftfile (/var/lib/ntp/drift) does not measure the difference between the local time and the time calculated by ntpd based on time. Set the hardware clock from the system clock; There’s a simple tool you can install called chrony that keeps your server time in constant sync. Just before shutting down the system, make sure the system clock is in correct time, then run > /etc/adjtime; If your servers are x86* the hardware rtc might be the source and some cron job the.
