I've set timeDayDivisor to 48000 to match my Time and Wind settings (36000 day + 12000 night).

This seems to work for infoTimeWorld but as far as I can tell has no affect on infoWorldTimeFormatted.

(I also suspect I'd need equal day/night lengths for things to match properly but I want to make sure I understand the situation. )

btw time and wind has method located in TimeAndWind.class which can be used for retrieving time in 24h format for current world. So if you will decide to add compatibility for my mod you can use it for time display.
