A simple application to see Local and Zulu time (GMT) or multiple time zones in a single glance. Useful for pilots in getting weather briefings and filing flight plans, or Ham radio operators to do timezone conversions. No more worrying about getting the timezone offset correct or Daylight Savings Time conversions. Easily convert from different time zones, including times in the future or past.

On the iPhone:

- The Zulu Time page gives a quick view of both Zulu and Local times

- The Offset Time page allows you to see Zulu and local time either in the future or past by entering an offset via the Offset button. Tapping either Zulu or Local times will allow you to enter a time in the future or past, synchronizing both Local and Zulu times with that offset. The offset only applies to this view (except on the iPad the offset applies to everything on the page)

- The Multiple Zones page allows you to add as many time zones as you wish in a scrolling view. Clicking on any Time Zone will allow you to change it.

What’s New

Version 3.2

- Fixed the default Mountain Time zone to not be based in Phoenix so it will respect Daylight Savings Time.
- Fixed a potential crash that could happen if you were upgrading from a very old version of ZuluTime
- Per user request, changed the color of the text in the Today Extension to be more legible

Needs complications!

This app is great, except it doesn’t have the one thing I needed and purchased it for: complications! See, Apple already lets you see UTC time and even includes it as a complication. But in order to see UTC or “Zulu” time in 24 hour time mode, you have to switch the entire clock to 24 hour mode. What I need to do is be able to see local time in 12 hour mode but Zulu time in 24 hour mode as a complication on the same watch face! It’s so frustrating that neither Apple includes a way to do this, and developers haven’t come up with UTC time app that has complications! And if they did, I would imagine they would inadvertently make it so that the 12/24 hour system setting dictates whether the complication displays in 12 hour or 24 hour mode, which would put me back at square one. Please make a complication for this app, and leave the time in 24 hour mode or make it an adjustable setting and not based on the system clock. Thank you!

Unfortunately Apple’s interface makes this difficult if not impossible to achieve. The tools they provide for displaying a time will not allow you to specify 24hour format, it goes with what the region the watch is in specifies. It also does allow you to build your own because you can’t update the time accurately. I’ll continue to look into, but so far I haven’t been able to get it to work. Thanks for the feedback.

Does what it says, but needs complication

For 99 cents the app is ok. Would be worth more and reviewed higher if it could be used as a complication rather than just an app and agree Zulu should be in 24 hour format. Developer mentioned this is difficult to do and keep clock accurate but I rarely need a real time count of the seconds. Make the complication by creating your own time digits, drop the seconds so update once a minute, and options for 12/24 format on local and/or Zulu

I’m still working out how to do that. Apple restricts the number of time you can update a complication per day. If you exceed that, the complication would cease being updated and just have the wrong time. I really want to do this, but it is challenging with the current API. I am looking into though, thanks for the feedback

Awesome App!

Now I can convert time zones to Zulu time in a snap. It has a very nice and intuitive interface. The only thing I wish it had was another button at the bottom that showed you a US map with time zone divisions to show which time zone each state is in.
