zdump — timezone dumper
zdump [−−version] [−−help] [−v] [ −c.RI [ loyear fB,fR ] hiyear ]
[zonename...]
Zdump prints
the current time in each zonename named on the command
line.
These options are available:
−−versionOutput version information and exit.
−−helpOutput short usage and exit.
−vFor 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 Daylight Saving Time or isdst=0 otherwise.
−c [loyear, ]hiyearCut off the verbose output near the start of the given year(s). The output still includes the lowest possible time value and one day after it, and the highest possible time value preceded by the time value one day before it.
