This is a workflow I created; which has had a few changes, fixes and improvements by other contributors over time.
The code is on Github and Packal; and had been posted on the Alfred Forum a while ago:
It can epoch timestamps to human-readable date/time; or the other way around. It will try to convert automatically what is in the clipboard, and show the results when relevant. It handles different epoch units (second, millisecond, microsecond, nanosecond) and different human date/time precisions (year, month, day, hour, minute...), and shows results in local and UTC timezones. It tries to always do the most convenient thing possible, and works without configuration.
It uses a fairly basic library to build the workflow, that is all packaged in, and the system's Python 3 interpreter. There should be no other dependency.
