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".
