Add display time zone option to "Timestamp"

Add time zone option to "Timestamp"

Expected Behavior

For circumstances where it is not feasible to display the date/time in user's time zone but instead must use a global reference, need the option to display the time zone (e.g. "UTC") in the time stamp.

Actual Behavior

There is currently no option to indicate (within the timestamp) what time zone is being referenced.

@alansouzati #1353 does not address this timezone issue

sorry github closed it automatically.

this would require another package that handles timezones with names like America\Los_Angeles which seems very vendor specific.

It is likely the timestamp will be removed in 2.0 as it is just a tiny wrapper around moment-js.

I don't see ourselves adding much more support for timestamp as it stands today. I'm going to close this issue because of this reason.
