How does my clock keep accurate time?

Hi, All--First-time poster with a perhaps ignorant question. I'm running a "re-flashed" (?) Lenovo Libiquity Taurinus X200 laptop with Trisquel 7.0.
I've never let it on the internet, for which I use another Apple computer. Despite not being on the internet, the laptop keeps accurate time. It can't be doing this internally, because the timing would gradually drift into inaccuracy, which it has not done. Somehow, it must be getting correct time from some outside wource.
How?
Thanks for any response,
Brian Donnell
All computers have a internal battery to keep the clock going even if it is poweroff.
If you mean about daylight time changes, if your country hasn't changed the policies then the dates to change since trisquel 7.0 (extremely outdated) will still match when to change the daylight time change.
Other than that, when your internal battery fail then you'll likely start to see the inaccuracy.
By default trisquel doesn't install program that make remote connections, timesync included.
For such cases we have documented how to enable it: https://trisquel.info/en/wiki/enable-time-synchronization-ntp

Thank, Ark, but I still am puzzled. I understand that the clock will run as long as it is powered. But in the absence of any external connection to GPS, Fort Collins, NIST, or internet, the clock time would drift, becoming increasingly inaccurate. This it does not do. I'll look at the link you provided; perhaps the computer came with time sync already enabled.
Thanks, Brian
So--I used the status instruction on the link you provided:--NTP is enabled, but not sync'd; RTC in local TZ is off. So I'm assuming that the computer is getting its time from some local NTP server.
Thanks again,
Brian Donnell
