Question

Is it possible to make either a jailbreak app/tweak or regular app that could display two times on the status bar on iPhone? Is such a thing possible and / or that’s already developed?

I have a very special friend in another country and sometimes I forget what time it is there. Having to check the time on the clock app is a pain, especially when talking on the phone. I can’t imagine a simple clock could use many system resources.

Definitely, most likely using MobileSubstrate. What I can imagine as a solution is roughly:

1. You hook into one of SpringBoard’s initialization methods.
2. You create an UILabel and add it to the status bar as a subview using the addSubview: method.
3. You spawn a timer (use NSTimer, Grand Central Dispatch or whatever suits you) to update the text of the label every minute or so. You can use NSDate and perhaps NSLocale (I don’t have the docs in front of me right now) to find out the local time of another country.
