Recently, I had a conversation with a junior developer on my team. Let’s call him Alan. We were talking about a new notification feature that was going to be used to send reminder e-mails to potentially thousands of people if they had forgotten to enter certain data in the last month or so. Alan was confident that the code he’d written was correct. “I’ve tested it well.”, he said…

    I had a client whose clock was just a few milliseconds behind the server’s, but due to timezone crap one hour in the past. And the signature was valid for one hour.

    If the network just happened to be too congested, the validation failed. The next request went through just fine. Took us forever to find out.

        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.

      I sure do hate time zones.
