Yesterday I have written a blog entry with a small program to calculate date and time from a given Unix time stamp.
Like my HP41 I have used an HP48 for a long time (I am using an HP50G until today). There are several emulators for HP48 calculators (Android, iOS and so on). I am running such an emulator on my Android phone. So I have written the same program for the HP48.
If you like it, I am happy. It’s not a program to solve the problems of the world but it’s still useful for a simple job.

Simply enter the Unix timestamp (number of seconds) and run the program. The resulting date and time is shown in a message box.
