Date and Time in Win 2000

Hi There.
I would like to give user ability to change time and date without making him/her a member of “Power user” or “Administrator”.
In Windows 2000 if a user is definedas a member of domain without any rights he/she cannot change the system time or even open up a calender. I would like to give user this right without givivng him/her any power user rights.
Any suggestions Please.
Thanks in advance.
