You need to convert the strings to numbers and do the arithmetic. It's as basic as that.
Assuming that your -date1- and -date2- are Stata daily dates
gen elapsed_time =
24 * (date2 - date1)
+ real(HH2) - real(HH1)
+ (real(MM2) - real(MM1)) / 60
That's one command, just spaced for legibility.
Stata 11 offers full support for date-times.

I am using Stata 10 and I would like to calculate the elapsed time, in hours, between two time points. My data is formatted as below, the hours and minutes are separate string variables.
variable: date1 HH1 MM1 date2 HH2 MM2
----- --- --- ----- --- ---
format: date str str date str str
I would appreciate very much your assistance in finding a way to solve this or indicating me any related link.
