Routine Description:
|
||
|
||
This routine calls the Win32 and NT base timer APIs to get the
|
||
relevant time/date information. It also calls the Rtl routine to
|
||
convert the time elapsed since 1-1-1970.
|

The routine allocates a buffer to contain the time of day information
|
||
and returns a pointer to that buffer to the caller.

Arguments:
|
||
|
||
bufptr - Location of where to place pointer to buffer.

Return Value:

NTSTATUS - STATUS_SUCCESS or reason for failure.
