Difference between two dates

[#1]

Hi!,

I have two dates and i want to calculate the difference between the two in hours. Not sure which function i have to use or how to go about it . Can somebody throw some light on this.

Also in other requirement i want to subtract 2 hrs from my time stamp.

The format in which in which i am getting date and time from SQL is '2012-02-22 13:20:00.000'

Thanks in advance.

You can try this.

Interval( End - Start, 'hh:mm:ss' ).

Interval(End - Start - (2/24), 'hh:mm:ss')

in order to get 2 hours less

for 2 hr less i dont want the difference in hrs. i just want to subtract my timestamp by 2 hrs and then compare it with other time stamp. so i just need to subtract 2 hrs and want the result in same format.

Hi,

     Try with interval function.

     =interval(EndDate-StartDate,'hh') which will give you hrs difference.

     For subtracting 2 hrs use expr below

     =Timestamp(Num(Date)-(2/24)) which will give you subtraction of 2 hrs.

Hope it helps

QV uses numbers to represent timestamps, so is the same to substract 2 hours to the total or to the last timestamp.

[fernando_tonial]

try this.

interval( (End-Num('02:00'))-Start, 'hh:mm:ss' )

OR

Time(interval( End-Start, 'hh:mm:ss' )-Num('02:00'))

OR

Time(interval( End-Start, 'hh:mm:ss' )-(2/24))

Best Regards.

Hi! i am getting my date and time in 12 hr format i.e 23/02/2012 5:44:03 PM i want it in 24 hr format like

2011-09-11 10:38:48.000

Hi,

If you're using the time function you can add formatting

using previous example

Time(interval( End-Start, 'hh:mm:ss' )-(2/24),'hh:mm:ss') should give you 24hours format.

by Using "Timestamp(Num(Date)-(2/24))"  using date as "2012-02-22 15:19:00.000"

i am getting two hr difference but i am getting the result in AM/PM format like    22/02/2012 1:19:00 PM i want the result as 22/02/2012 13:19:00
