Can´t use duration notation for x_interval

[Luc Heijst]

In skin.conf duration notations like 3h, 1d, 1w or 366d, can be used for time_length and aggregate_interval.
When used for x_interval, like 1h or 1d, an error occurs, see below.

Is this a bug or done on purpose?

I'm using weewx version 5.3.1 and python 3.13.5
