As a web developer, I've been using this app for years and love it! It's very handy to be able to quickly see what the current UTC time is.The one feature I wish it had is having a fixed width (perhaps by having an option to use a monospaced font). As it is now, the menu bar icons I have to the left of UTC Bar shift as the seconds tick by because the width changes.

It is a nice simple app, with intuitive choices for setting up what format you want it to use to show the time and date, if you so choose. It does what it says it does. I would have given it a five star rating, but I soon realized that it does not open at login by default which is what I want it to do. After opening the app I realized that it does not have an option to indicate that you want it to open at login in its own preferences. I looked for it in the dock, but it was not there. So neither of those ways that I was familiar with for getting apps to open at login were available. When I came back to the App Store to try to contact the developer to get support in getting it to open at login, I found that Safari could not find the server for either the “UTC Bar Support” link or the "Michael Hasak Web Site” link, the links given on the apps App Store page for the app. It would have lost two stars but I continued my troubleshooting and found that I could add it to my login items by going to the “Login Items” tab of my User Account in the “Users & Groups” window of System Preferences and adding it there. It lost one star for the inconvenience of having to do that, for not being designed to have a simple preference option to choose whether or not you want it to open at login, and for having non-functional links for support.

I’ve been using this utility while working through flight plans (it is so nice to have zulu time visible at all times). The developer is very responsive to feature requests, and I’ve never had any issues with UTC Bar. I would recommend this app without hesitation to anyone who needs quick access to UTC time. Thanks, Mike!

I need Zulu time in working with flight plans. I’ve tried several other clocks, and I’ve been disappointed. This one does exactly what I need, no more, no less. And I didn’t have to fiddle with it to figure it out. If you need Zulu/UTC, this is the app.
