Betreff: st: Formating a date to a local macro variable

I have a variable "date" that contains the date that a particular assay was
run (the variable is in a data format). I would like to assign the date in a
particular observation to a local macro variable (its the same date for all
observations). Currently when it does this it assigns it a number in stata
date format relative to Jan 1, 1960. Is there a way to assign it to the
local macro variable in a way that it will formatted in a "readable" date
format?

		quietly sum date if tmp_dp ==`i'
		local date = r(mean)

Thanks,

Susheel
