Below is the original “tweet”, time stamped @ 8:02 PM. Not sure why the other time stamps are misdated like that. Definitely odd, but probably isn’t significant.
And as someone mentioned, this is being reported on FOX news.
It all depends on who did the screen grab, not the time of the tweet. It reflects the viewers local time.
Saudi Arabia is apparently 7 hours ahead of Eastern Time. http://www.timeanddate.com/worldclock/city.html?n=214
