Show HN: Pole Clock, a single 24h clock with multiple timezones
Hi HN! I designed this Pole Clock to be a helpful tool for people
like myself who often struggle with managing their sense of time.
I found that analog clocks are generally easier to read and
understand than digital ones, however I find the fact that every
day is broken into two 12-hour rotations unintuitive. A single
24-hour rotation makes it easier to grasp where in the day you are,
the bottom half representing night and the top half representing
day. Additionally, because the clock displays 24 hours, you can
add extra hour hands on the clock for other time zones. This is
especially useful if you work remotely or have friends and
colleagues in different time zones. At a single glance, see where
they are in their days and energy levels! I hope you'll give the
Pole Clock a try and find that it helps you better understand and
manage your sense of time.
