Hello Thomas,
thank you for your reply. I know that I can get date and time from
Stata code. But I need to determine it within a procedure in Mata,
possibly without quering Stata (without having to use function stata()
). As it is described in another post here, macros are evaluated
during the compilation time, and this is the reason that my code does
not work as it is supposed to.
Thanks, Sergiy
