Check overlap of dates along with time component

Hi all,

Is there a FM to check if a group of date and time overlaps?

For example: If have start date, start time and end date and end time for one date and time range. Now there is one more date and time range(start date, start time and end date and end time) which i need to check if it overlaps the first.

Any ideas??

Thanks
