If you live right on the border of two different time zones, or you’re close friends with someone who lives in a timezone different than yours, then you may want to stay mindful about the variances in time across several regions as not to come off as disturbing to someone else when you send a text or place a phone call.

Apple’s native Clock app is an excellent resource for checking the time in other time zones, but if you’ve ever wished you could tell the time in another location at a glance without having to launch an app, then you’ll probably come to appreciate the likes of a newly released jailbreak tweak dubbed DualClock by iOS developer exodia9610.

Just as the tweak’s name implies, and further supported by the screenshot example above, DualClock puts two separate time and date indicators on the Lock screen so that you have fast and effortless reference to the current time in another timezone at a glance.

DualClock is fully configurable. Not only can you choose which time zones are depicted by each individual clock, but you can also configure date and time formatting, among other things. All these options and more are available via a dedicated preference pane in the Settings app after installation:

Here, you can:

  • Toggle DualClock on or off on demand
  • Configure a preferred vertical positioning
  • Choose a time zone for the first clock
  • Choose the date format for the first clock
  • Choose the label for the first clock
  • Hide or show the A.M./P.M. indicator for the first clock
  • Enable or disable 24-hour time for the first clock
  • Choose a time zone for the second clock
  • Choose the date format for the second clock
  • Choose the label for the second clock
  • Hide or show the A.M./P.M. indicator for the second clock
  • Enable or disable 24-hour time for the second clock
  • Hide or show the seconds indicator
  • Hide or show the Face ID Lock
  • Hide or show the charging indicator
  • And more…

The developer provides a Respring button at the top of the preference pane to help you save any changes you make on demand.

One of the things I like best about DualClock is that it integrates into the native Lock screen interface in a somewhat Apple-esque way. If Apple were ever to make a feature like this, this is ultimately how I would envision the company making it, as it’s both simple and useful.

Those interested in trying DualClock can purchase the tweak for $0.99 from the Packix repository via their preferred package manager. The tweak supports jailbroken iOS 13 devices.
