dm_zdump [-v] [-c YEAR] [ZONE ZONE ...]
- -h, --help
- Print online help.
- -v, --verbose
- This displays all critical dates (i.e. the times when a time change occurs
due to the timezone description) for each of the timezones listed (or the
local timezone if none are listed).
Each critical date is printed as two lines of output: the last second before the change occurs, and the first second of the new time.
By default, all critical dates from Jan 1, 0001 until the year 20 years in the future are printed, but this can be changed with the -c option.
- -c, --cutoff YEAR
- This specifies the cutoff year. All critical dates up to the start of YEAR are given. The GMT time Jan 01, YEAR at 00:00:00 is the cutoff time.
