Same as other `formattime`, but does not accept timezone. Instead, it uses system's local timezone.

These are variables that are always there, without you having to import them.
The delay between the updating variables is always 2s.
The delay between all the updating variables except `EWW_TIME` is 2s, for `EWW_TIME` it is 1s.
