NAME

       Tcl_GetTime - get date and time

SYNOPSIS

       #include <tcl.h>

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.)
