It sounds like you're after an NTP daemon.
From the manual page for ntp.conf:
driftfile driftfile
This command specifies the name of the file use to record the
frequency offset of the local clock oscillator. If the file
exists, it is read at startup in order to set the initial fre‐
quency offset and then updated once per hour with the current
frequency offset computed by the daemon. If the file does not
exist or this command is not given, the initial frequency offset
is assumed to be zero. In this case, it may take some hours for
the frequency to stabilize and the residual timing errors to
subside.
The file format consists of a single line containing a single
floating point number, which records the frequency offset mea‐
sured in parts-per-million (PPM). The file is updated by first
writing the current drift value into a temporary file and then
renaming this file to replace the old version. This implies
that ntpd must have write permission for the directory the drift
file is located in, and that file system links, symbolic or oth‐
erwise, should be avoided.
All the best,
Chris
