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 provides.  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 single-processor Windows  systems,  the
       usec field is derived from a performance counter and is highly precise.)
