I have no reason why the Capitol Police would be using the DC time when monitoring something in a different time zone. If it was me I would want to know what the time was that I was watching. Listen if I were monitoring a situation I would want to know what the time was for the thing I was monitoring. If I’m looking at something in Tokyo, I don’t want to know what time it’s in DC. Just saying. And for that matter what day it is because they could be different.
I’ve been to Tokyo and I left from DC on Sunday morning and arrived in Tokyo on Monday evening. And on the way home I left Tokyo on Saturday evening and arrived in San Francisco on Saturday morning. So I would really like to know what the time was there and not here
