minus-squarePhrodo_00@lemmy.worldlinkfedilinkarrow-up2·7 months agotz offset is really not enough. You’d need to save the time zone id and/or offset, to have you library calculate deviations such as daylight savings. Even that, that would break if the user moves and now what they setup is using their previous timezone. Basically, I’m saying that storing the offset works most of the time, but not all of the time.
