One or two requests, date and you may style, are accustomed to convert a sequence big date into the a good numeric time.

Significantly more than, our very own go out string try formatted go out, week, 12 months, and no reputation splitting up different areas of the big date, but not, Stata are capable of many formats and you may ple, all of our study might have been noted “20-” plus the purchases a lot more than works without any changes.
