I don't understand your timezones and all the different abbreviations. We just have the one - GMT (or some people use BST when it's Summer)
If I got this right, according to Google it's 6.24pm in EST and 5.24pm in MST. It's 12.24am here, Saturday
Where exactly are these timezones?
MST is the Mountain timezone. The coolest of them all. Then there's central, pacific, atlantic, and eastern zones, all of which correspond to where they sound like they do (except eastern, which is in between central and atlantic).
That doesn't help, that's UTC +/-
