Absolute

   Absolute time includes a specific date or time of day. An
   absolute date/time has one of the following formats:

	dd-mmm-yyyy 
	hh:mm:ss.cc
	dd-mmm-yyyy:hh:mm:ss.cc
	"dd-mmm-yyyy hh:mm:ss.cc"
	BOOT
	LOGIN
	TODAY
	TOMORROW
	YESTERDAY

   You can omit any of the trailing fields in the date or time. You
   can omit any of the fields in the middle of the format as long as
   you specify the punctuation marks, for example, "-mmm-yyyy hh".
