       --help Output short usage and exit.

       -v     For  each zonename on the command line, print the time at the lowest possible time value, the time one day after the lowest possible
	      time value, the times both one second before and exactly at each detected time discontinuity, the time at  one  day  less  than  the
	      highest possible time value, and the time at the highest possible time value.  Each line ends with isdst=1 if the given time is Day-
