st: Efficient code to generate many date/time variables at once

[Alison El Ayadi <aelayadi@gmail.com>]

Dear Statalisters -

I have to create a number of date/time variables using a %td formatted
date and a string time, which I generally do using the following code,
for each of the different time points -

gen dt_tm_drape_str = string(dt_drape,"%td") + " " + tm_drape
gen double dt_tm_drape = clock(dt_tm_drape_str,"DMYhm")
format dt_tm_drape %tc

I'd like to make my code more efficient by having it run through all
of the variables that I have, which are paired as dt_X and tm_X.  Any
suggestions on how to put together a program to do this?

Thanks,
Alison
