No You should run ntp or chrony (which can also keep track of your rtc
performance so on reboots the time is correct)
iThey continually keep the clock updated, going to the web for more info
depending on the reliability of your system clock, and advancing or
retarding the time to compensate for problems. Note that ntpdate will
advance or retard the clock in jumps, which can cause problems
especially on a server where file times change a lot. A jump back can
screw up file operations apparently due to the use of time info for
determining if files are newer or older.
