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?

I do not believe it is possible to have EnergyPlus report in daylight savings time instead of standard. For specific reporting purposes you could post-process. Do you have a specific use case in mind?

Thanks for the reply - for now I've been handling it via post processing but was hoping EnergyPlus might be able to do it for me. I'm modeling impacts for actions to demand response (DR) events that occur on specific days; was wondering why my summer DR events appeared to be an hour off in post processing and discovered it was due to daylight savings time.

Just wanted to add, I found an output variable in the .rdd file called Site Daylight Saving Time Status that is either a 0 (standard time) or a 1 (daylight savings time) - can make post-processing the output easier to key off of.
