timezones option on alarms (for frequent travelers)

[gh69]

Feature request: Add the option to select the timezone of each alarm, perhaps with a default of CURRENT TIMEZONE so as not to effect the majority of people who rarely leave their home time zone. For those of us who travel regularly across timezones it is a pain and often errorprone to have to remember timezone offsets when creating an alarm for use outside of your home timezone. This is also helpful for vacationers...for example if I live in New York, New York, US and know that I have a tour bus meeting me next Monday at 7am at a hotel in Tokyo, Japan, and I need to set an alarm to wake up on time, having to calculate that time difference up front and set the alarm at the right time on the right day is way to easy to mess up. If I could simply enter the alarm as a Monday 0600 alarm in the Japanese timezones it would be perfect.
