  3. Help me to add time to a date and time
    I will explain my problem with an example.

    30/01/2009 13:30 is the time.I want to add 36 hrs to it.

    But I should add it only during the working hours.(8:30 hours per hour a day(exclude week ends and holidays)).

    Assume working time to be from 08:00 to 16:30

    So the time after 36hrs added would be 05/02/2009 16:00.


    I can add only the date through workday function,which also excludes holidays and weekends.But I am not able to add the exact time.

    Can YOU help me to get it done through macros??

    Thanks in Advance
