See Overlaps For A Set Of Time Zones

The tz command (brew install tz) will display by default your local time and UTC for comparison. By including the TZ_LIST env var with a semi-colon separated list of time zones, you can display several time zones to see how they compare. The results are even color coded for working, flex, and non-working hours.
