timezone

Hi!

I have 2 date object in the database that represent the company's working hours.

I only need the hours but since I have to save date. it appears like this:

Date companyWorkStartHour; 
Date companyWorkEndHour;

start hours: 12-12-2001-13:00:00 finish hours: 12-12-2001-18:00:00

I have the timezone of the company and of the user. (my server may be in another timezone).

TimeZone userTimeZone;
TimeZone companyTimeZone;

I need to check if the user's current time (considering his timezone) is within the company working hours (considering the company's time zone).

How can I do it? I am struggling for over a week with Java calendar and with no success!
