How to parse EDT time zone?

General Usage
1

For example, I have the following time “2012-01-09 12:00:10 EDT”. How do I parse it to a ZonedDateTime using TimeZones.jl? “EDT” is not a standard time zone, and tz"EDT" fails to parse. The thing is I want to make it general, so that both “EDT” and “EST”, and other time zones work.
