It appears EnergyPlus can account for daylight savings time but doesn't update the timestamp in hourly output - from this it sounds like hourly output timestamps are not shifted ("reporting is always in standard time") but schedules are: https://bigladdersoftware.com/epx/docs/8-5/tips-and-tricks-using-energyplus/schedules-off-by-1-hour.html
Is it possible to have EnergyPlus output daylight savings time instead of (or in addition to) standard time?
