compare datetime

I need to do a datetime comparison that takes a string argument such as 9:00 AM and compares it to the current datetime on the server.  

So, if I wanted to compare 3/20/2012 9:00 AM > 3/20/2010 1:00PM it should be false because 9:00 AM is less than 1:00 PM.

One other issue is the time on the server is GMT and I need to translate that time into Mountain time (Phoenix, Arizona).

I'm posting in the java forum, but I'm writing this code in Apex (Salesforce language), which is a derivative of the Java language and is compiled on a Java App Server.  One issue is Apex does not have the Java class library available, so I have to write this from scratch.

Any help is appreciated.
Thank you.

>>> 3/20/2012 9:00 AM > 3/20/2010 1:00PM


that is true when you compare them as strings.
either reformat them to be sortable strings (yyyy/mm/dd HH:mi:ss - where HH is 24-hour clock)

or, convert the strings to datetime types

to convert a string to a date try something like this...


Datetime dt = DateTime.parse('3/20/2012 9:00 AM');

Java has a lot of functionality associated with dates - if none of it is avaialable in Apex, it is not clear how you can do it
