Subtract 5 hours from a Date / Time field

Hi,

 

I'm creating a date / time formula field in which I would like to keep te time of another date time field and subtract five hours from it.

 

For example, in field A I would have "11/23/2010 9:03 PM" and in field B (the formula one I should see "11/23/2010 4:03 PM"

 

 

Is this possible?

 

Thanks

Let me know if you find any issues.

Just in case anybody else was wondering (i.e. you need to subtract or add more or less than 5 hours) 1/4.8 = 5 hours because it is taking 1 day and dividing it by the quotient of 24hours / number of hours. 24 / 5 = 4.8 or 24/4 = 6 (1/6) .  4 hours is 1/6th of a day.  5 hours is 1/4.8th of a day.

Instead of (1/6) You have to use (DateTime - (1/6.0)) for 4 hrs subtraction
(DateTime - (1/8.0)) for 3 hrs subtraction 
(DateTime - (1/12.0)) for 2 hrs subtraction
(DateTime - (1/24.0)) for 1 hrs subtraction

have a nice day!!

How can we substract 5 minutes from DateTime. 
DateTime d = (System.now()- ((24/1440.0)/5.0)) will it work?
