It's you who's living in the past. :-)

A similar though subtly different use case is putting an appointment in your calendar when you're currently in a different time zone than the appointment will be. And the fact that we now carry devices in our pockets that get used for stuff like this makes it far more likely that stuff like this will come up - though it can happen without you even moving time zones. For instance, at a previous job, we were supposed to mark in Outlook when we were taking PTO, and I was in a different time zone from my eomployer. And since Outlook treated makring a day as marking a specific 24 hour period, I'd mark a day on the West Coast and end up with it showing something like 03:00 - 02:59 when folks looked at it on the East Coast. And if you didn't look at the exact times when looking at it on the calendar, I think that it managed to make it look I was taking two days off instead of one.

Coming up with a way to deal with stuff like this in a way that doesn't run afoul of time zone problems can be really hard - especially since people don't tend to think about these things the same way computers do. The absolute vs relative path analogy is an interesting one though.

It's been fading away since I was a teenager.

It's nice to not have to worry anymore about hair gels, blow dryers, expensive hair cuts, bed head, helmet hair, getting it caught in the drill press, feathery creatures nesting in it, etc.

Wait a moment! This has nothing to do with time travel, does it!??! :)
