Syntax question

If I create an automation, say, using an offset in sun, the offset is enclosed in single quotes:
‘+00:31:00’
However, reading the help (sun implementation details), the offset example is in full quotes:
“-01:00:00”
Which is correct? Or does it even make a difference?

They are, as far as I know, the same.
You can use one if your string contains the other, so you avoid having to use special characters or special combination og characters.

Very cool.
Thanks!
