Tcl_GetTime(3)                             Tcl Library Procedures                             Tcl_GetTime(3)

NAME
       Tcl_GetTime - get date and time

SYNOPSIS
       #include <tcl.h>

       Tcl_GetTime( timePtr )

ARGUMENTS
       Tcl_Time *   timePtr   (out)     Points to memory in which to store the date and time information.
____________________________________________________________________________________________________________

DESCRIPTION
       The Tcl_GetTime function retrieves the current time as a Tcl_Time structure in memory the caller pro-vides. provides.
       vides.  This structure has the following definition:
              typedef struct Tcl_Time {
                  long sec;
                  long usec;
              } Tcl_Time;

       On return, the sec member of the structure is filled in with the number of seconds that have  elapsed
       since  the  epoch: the epoch is the point in time of 00:00 UTC, 1 January 1970.  This number does not
       count leap seconds - an interval of one day advances it by 86400 seconds regardless of whether a leap
       second has been inserted.

       The usec member of the structure is filled in with the number of microseconds that have elapsed since
       the start of the second designated by sec.  The Tcl library makes every effort to keep this number as
       precise  as  possible, subject to the limitations of the computer system.  On multiprocessor variants
       of Windows, this number may be limited to the 10- or 20-ms granularity of the system clock.  (On sin-gle-processor single-processor
       gle-processor  Windows  systems,  the  usec field is derived from a performance counter and is highly
       precise.)
