    I am trying to write a Java script that will be in an html page. The script needs to tell us when it is 4:30 in different time zones so that we can make any last minute calls before they close. So at 1:30 it will tell us that 4:30 is coming up in New York so make your calls now.

    Thanks for your help in advance

    I realize this post is a month old, but I only found this site this morning.

    The source below should get you pointed in the right direction.
