Epochs aren’t that simple either.
First of all, local time can be relevant, so you have to store timezone information somewhere anyway.
Epochs are also somewhat iffy in regards to leap years or seconds.
And finally: write me an SQL to retrieve all entries submitted in 2022 using just epochs.
Timezones are annoying as fuck, don’t get me wrong, but simply ignoring them isn’t a solution either.
You can’t really bork your system, since you can’t always roll back and since the entire system is declared in one file (tree) that should work flawlessly.
In case of servers: the entire config is in one place. That can make maintenance much easier. At least for Homeservers. If you’re deploying a fleet, puppet or ansible might be the better tools.
