NAME
     Tcl_GetTime - get date and time

SYNOPSIS
     #include 

     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  multiproces-
     sor  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.)
