💖 DM_ZDUMP — timezone dumper 💖

okay so real quick, bestie: this is dm_zdump, from the User Contributed Perl Documentation corner of the manual-verse (that's the DM_ZDUMP(1) zone, iykyk). it's the timezone dumper and it's lowkey iconic.

✨ SYNOPSIS ✨

so this does the exact same thing as the unix zdump command, except it does it through the Date::Manip module instead. same energy, different engine 💅

dm_zdump [-v] [-c YEAR] [ZONE ZONE ...]

🌸 DESCRIPTION 🌸

by default it shows you the current time in every ZONE you name on the command line. and if you don't pass -v? still just the current time, bestie. that's the whole vibe.

  • -h, --help — prints online help. that's it, that's the flag 🫶
  • -v, --verbose — this one's the main character. it displays all critical dates (aka the times when a time change happens because of the timezone description) for every timezone you listed — or for your local timezone if you listed none. no cap.

every critical date gets printed as two lines of output: the last second before the change happens, and the first second of the new time. two lines, one glow-up. 😭

by default, all critical dates from Jan 1, 0001 until the year 20 years in the future get printed. you can change that with the -c option, obviously.

  • -c, --cutoff YEAR — this sets the cutoff year. all critical dates up to the start of YEAR are given. and the exact cutoff time is the GMT time Jan 01, YEAR at 00:00:00. precise. periodt. ⭐

💀 KNOWN BUGS 💀
