How can I put the current date and time in my log files?

You can put the current date and time into your log files by displaying the global macros where these values are stored.

For example,

 . display "$S_DATE"
 14 Feb 2003

 . display "$S_TIME"
 15:53:01

 . display "$S_TIME  $S_DATE"
 15:53:17  14 Feb 2003

The current date and time are also available as part of the c() class, see [P] creturn.

 . display c(current_date)
 14 Feb 2003

 . display c(current_time)
 15:56:05

 . display "`c(current_time)' `c(current_date)'"
 15:56:32  14 Feb 2003

David Kantor suggests the following ado-file:

 *! version 1.0
 * Datetime procedure.  Just displays the date and time.
 * Good for use in logged sessions.
 * By David Kantor.  9-26-97
 version 7.0
 program define datetime 
 disp "DateTime: $S_DATE $S_TIME"
 end

It is then easy to include datetime in your do-files.
