Useful when working with timestamps

When i am in the terminal or in my dev tool, and work with databases timestamps its very useful to convert quicly and easily timestamps.
To have in the same time UTC and local time zone conversions is a good idea.
Just difficult to find the appli in appstore, when i search "timestamp" i was not able to find it. I hope this comment will help.
