Developer Response
Dear User,Thank you for your feedback and for using our app! Denver (Mountain Time) is indeed included in the list of time zones. As a major timezone, it is set as a favorite by default (with a star) and can be found at the top of the list, between Chicago and Los Angeles. This might have caused some confusion since it does not appear in the alphabetically sorted list that follows. We hope this clears things up!Best regards,--Shift Unit
Must have- Simply Awsome

- Added backward compatibility for older versions that may not handle the newly incorporated currencies (SLE, XCG, ZWG)
