Not especially. My everyday timepiece is an MSF wall clock, which agrees

a couple of seconds late.

That is because Windows syncs itself by default once per day at a set
time of day. If your PC is not turned on at that time, it will not sync
itself, so it then has to rely upon its internal (not very accurate)
RTC.

You can download a free utility which allows you to set how often (how
many minutes) Windows should attempt to sync itself, from every few
minutes to once per day. Mine is set to sync itself every 30 minutes
and always agrees with my radio controlled watch.


And if you install a proper NTP client, it will try to maintain a drift
correction factor between NTP time and the local (kernel software) clock
which improves accuracy between NTP remote queries.

The Windows Time service is a NTP client and can be configured to set
the clock accurately.
