Not necessarily constant.

I guess it comes down to, exactly what kind of accuracy do you require,
and for what application? GPS will get you time to within a second,
but it's more expensive than occasionally syncing your PC to a network
time server which can do the same. If you have a particularly nasty clock
drift problem, sync more often (1/day instead of 1/week).

Now, if you can't ever connect to a global network, then something like
GPS is a good option. But we see a lot of people on here asking to
use GPS for getting the time for applications where something like NTP
can do the job for free. So, it's only natural that the regulars here
question the initial assumption.
