You still have to calculate the distance between a date on the DB and a date on the client, the timezone difficult issues are not sidestepped at all

Your server and DB are both UTC. If not, that's something you just need to fix. The server can then calculate the difference trivially. Then you no longer need to do anything on the client. Eg, this is what Django's timesince or timeuntil filters do: https://docs.djangoproject.com/en/4.2/ref/templates/builtins...
