So...does the post apocalypse embrace DST?

Does Eugene monitor the time and tell everyone to dial their watch back on certain days or they go on not worrying about it and when two groups have to meet on a certain day and time, how does it work?

Back then when the Saviors met with the Kingdom for pigs and produce, how did they set a meeting time? Do they all have a calendar? How did Michonne and Alpha set up day and time to meet? Next Tuesday, 6pm EST DST?

What if your group wander in the country for months and lost track, how do you get back on track if you need to?

 

So if they have a hand winding watch they will use that to keep time. If they ever forget to wind it and it stops they must find someone else with a watch to synch up?

When Morgan went westward did he synch with people he came across along his way?

"Hey fellow what time do you have? 4? Oh right this is Arizona so I need to dial back another hour, thank you!"

How do they keep track of the day of the week? Someone has to keep track, those with a day function wrist watch?

What about the day of the month? Who would remember how many days each month and which year February has 28 or 29 days? Can't rely on wrist watches for that.

 

That goes back to my original post where I asked...how did the saviors and the kingdom coordinate the day and time to meet back when the gave them melons and pigs? It seemed like the kingdom people got to the meeting spot, then a few minutes later the saviors got there. They must have had a way to figure out when - on both ends.

Didn't Rick meet with the governor inside a barn? They had a meeting time I assume, more precisely than "at dawn" or "after dark" or else people would be waiting a while due to not being able to pin time down. Unless as someone suggested they use a sundial, or mechanical watches that keeps running and running and running.
