I have a live dataset that has a time field expressed in UNIX (The amount of seconds passed since 1 January 1970).
I would like to add a new field to it containing the datetime of my timezone (GMT+1/Central Europe). The dialog box of Field Calculator (both default as Regular Expression) don't give much information on how to fill in values. Which of the two FC's can be used best for my task? And what does the function look like?
