Hi Users,
Sorry for all the inconvinces. I don't know if stata has some buildin
functions to handle time variables, as it does on date variables. I have a
variables looks like the following:
Obs. No. Time
1 2003-03-03 09:30:29
2 2003-03-03 09:30:47
3 2003-03-03 09:31:11
I want to calculate the duration of the time, which should be the first
order difference of time if time is defined as a kind of variable called
"time", as with the "date" format. I wish there is some buildin function so
that we can calculate 2003-03-03 09:30:29 minus 2003-03-03 09:30:47 will
equals to 28 seconds. Please help me if you know how to do it.
thanks
Levy Lee
