st: handling times and dates
I am trying to format dates and times so I can graph chunks of a large dataset using twoway line. I have the following variables to consider: date, time, V_max.
I want to graph V_max on the Y axis, with Time on the X axis, ideally grouped under Date.
The variable Time in my db is formatted as: "4:07:00 PM", with observations taken every minute. Stata incorrectly recognizes this as a date format. There seems to be no built in format to handle this type of data correctly.
The format for Date is "10/11/2004" - which is formatted correctly on input.
Is there any way Stata can
(1) handle the time variable in a way that I can graph AND process
(2) include date on the X axis (as well as time) automatically
