For those who don't have hex2date:

$ python -c "import datetime as dt;print(dt.datetime.fromtimestamp(int('68686868', 16)))"
2025-07-05 01:48:56

or:

$ python -c "import datetime as dt;print(dt.datetime.fromtimestamp(int('67676767', 16)))"
2024-12-22 02:12:07

or even funnier, the most evil day ever:

$ python -c "import datetime as dt;print(dt.datetime.fromtimestamp(int('66666666', 16)))"
2024-06-10 04:35:18

The digit seven is missing, so close, lol...:

23:48:56 we have, [2, 3, 4, 5, 6, (missing), 8]

Interesting. Bash is a wonderful tool. :)

My Python version also works on that other system...which shall remain
nameless. ;)

Agreed. :-)

My program works on fifty different platforms and I am
currently working to include all timezones, besides +0000 UTC. :-)

Africa is already finished.

Does that include BCE? :)

Only Gregorian or Julian also? How about Mayan? :)

No ... but here is a bash script, written by Bing AI, which
allows you to enter with -h hex values, or with -d decimal
values and prints to stdout all timezones. :-)

#!/bin/bash
# Assume the time is in decimal format by default
time_format="decimal"

# Check if arguments were passed
while getopts ":d:h:" opt; do
case $opt in
d)
epoch_time=$OPTARG
;;
h)
epoch_time=$((16#$OPTARG))
time_format="hex"
;;
\?)
echo "Invalid option: -$OPTARG" >&2
exit 1
;;
:)
echo "Option -$OPTARG requires an argument." >&2
exit 1
;;
esac
done

# Use the current time if no time was passed
if [ -z "$epoch_time" ]; then
epoch_time=$(date +%s)
fi

# Print the table header
printf "%-40s %s\n" "Timezone" "Local Time"
echo "---------------------------------------------------------------------"

# Write all available timezones to a file
timedatectl list-timezones > timezones.txt

# Output the local time for the passed Unix Epoch Time in each timezone
while IFS= read -r timezone
do
local_time=$(TZ=$timezone date -d "@$epoch_time" '+%a %b %d %Y %H:%M:%S %Z')
printf "%-40s %s\n" "$timezone" "$local_time"
done < timezones.txt

And here a sample run:

./tz.sh -h 68686868 > data.txt

data.txt:Timezone Local Time

Regarding my Go program, when it is finished ...

With 'date' and my program one can use it then as planner
for international online meetings. :-)

Example: Let's meet in sci.crypt on Sunday, June 23rd 3:00 PM
Central European Summer Time.

$ date -d '2024-06-23 15:00' +%s | go run hex2date.go -d -tz America

A similar thing for Python:
https://pynative.com/list-all-timezones-in-python/

With a little work I'm sure it's possible to do something like that AI
thing. Just for fun, here is the number of timezones it has listed:

>>> len(pytz.all_timezones)
596

Many are, apparently, not even in use. :) I suppose they are there for
historical reasons. Possibly future use.

Poor bastard! 4am. ;)

Not only is he probably quite lonely on that wee spot of land in the
middle of the ocean, he also has to be up at the crack of dawn if he even
wants to have any online company and talk with them in real time. ;)

Interesting, my program has 597.

I don't know. I just included all of them. ;-)

I have another program, which calculates the weekdays of your birthdays. :-)

$ bdates -tz Europe/Berlin 2020-xx-xx 2030-xx-xx
The birthday in the year 2020 was on a Monday
The birthday in the year 2021 was on a Tuesday
The birthday in the year 2022 was on a Wednesday
The birthday in the year 2023 was on a Thursday
The birthday in the year 2024 was on a Saturday
The birthday in the year 2025 is on a Sunday
The birthday in the year 2026 is on a Monday
The birthday in the year 2027 is on a Tuesday
The birthday in the year 2028 is on a Thursday
The birthday in the year 2029 is on a Friday
The birthday in the year 2030 is on a Saturday
and so on.

I wonder what else can be done with the Linux 'date'
command. :-)

Well, I suppose only one's imagination puts any barriers on that. I'm sure
there are ways to, if not by date alone, so by combining date with other
commands to get what you want.

Any ideas how to solve calculating the difference between two dates and
report back years, months and days, like an age of some thing, or a
person?

Like I bought my car on 2015-07-23, how old is it today? And how old will
it be on 2026-07-23?

That type of thing.

Example:
https://www.timeanddate.com/date/timeduration.html

I have a Python gadget that follows how that site does it, by excluding
the end date:

$ sky -d2age "1970-01-01--2024-06-16"
54 years, 5 months and 15 days.

$ sky -d2age "1976-02-29--2024-06-16"
48 years, 3 months and 18 days.
(In reality, since start year is a leap year, age is 12.0 years.)

I should really clean that result up a bit. :)

Yes, something like that. Another thing might be to combine the date
output with graphics, or cryptographic related things. I have to think
about that.
