I'm trying to create a code that will allow two users to setup a meetup time.

I have one table:

id - time - meridiem

Some sample data:

1 - 12:00 - A.M
2 - 12:30 - A.M
I also have a users table

id - user - timezone

some sample data:

1 - user1 - America/Denver
2 - user2 - America/El_Salvador

If user1 selects 12:00 A.M as the time, I want to convert it to show the correct time in the registered timezone for the second user whenever he views the time that was selected.

Anyone give me any ideas? Thanks so much.
