I noticed my system time is consistently some 6 minutes behind the official time (as seen on this website), which tends to make me late for appointments.
In the last session, I’ve manually synced my machine system time with the official one, using an appropriate sudo date command, but I’ve found on the next boot that the change is not persistent.
Here’s my system info (through $ inxi --admin --verbosity=7 --filter --no-host --width | xclip):

Looking for similar threads in the forum, I’ve only found this one, which methinks isn’t what I need; however the command below might be a helpful lead:
$ sudo timedatectl show-timesync
Failed to parse bus message: No such file or directory
What should I do to make sure my system time is synchronized (preferably with https://www.horariodebrasilia.org) every time?
