Time/date variables
Stata already had date variables; now it has time variables (and
time-and-date variables, too). Time is recorded with up to millisecond
resolution, which will be important for some. Also, Stata’s time
variables will work with or without leap-second adjustment. You may never
have heard about leap seconds, but there are clocks that are adjusted for
them, and clocks that are not, and in computer-generated datasets, time
stamps come both ways. Stata can work with either one.
You can now record values like 25jun2007, or 13:42:41.106, or
25jun2007 13:42:41.106.
Stata 10 has functions that make it easy to input date, time, and
date-time variables, so you can read data recorded as
June 25, 2007 1:42 p.m., or
6/25/07 13:42, or
250620071342106, or
Mon Jun 25 13:42:41 CDT 2007.
Stata 10 has formats that let you display date, time, and date-time
variables any way you want, including any of the above, and lots more.
