OK puzzle partly answered. Two people in different time zones, both without Twitter account, are shown the same timestamp on a Twitter post.
Anons, help us with a quick xperiment.
Let's look at POTUS tweet here:
https://twitter. com/realDonaldTrump/status/946201376652169220
Mine shows 6:09 PM on Dec. 27, 2017.
Now we need an Anon who DOES have a Twitter account to reply with their timezone and what timestamp they see.
Your reply should say whether or not you have a Twitter account, and what time zone your PC is set to. (Assuming you aren't using a VPN to access Twitter).
