Energy plus weather files UTC/GMT

I would like to combine results from monitoring and simulations and i would like to ask about the time issues. 1st hour of the epw means 00:00-01:00 average value? 1st hour of the epw means local time (clock time) without daylight saving time changes +1, -1 ? epw has solar position data? What is the relationship time and solar position for Denmark. I use Designbuilder soft. thanks

Energy plus weather files UTC/GMT

I would like to combine results i have data from monitoring and simulations a weather station (2014, 2015) and i would like want to ask about the time issues. 1st hour transform them to epw files. The first temperature of the epw means file (from 8760) is the average temperature from 00:00-01:00 average value? 1st hour (e.g. 2014 of my data) or the exact temperature of 00:00 (end 2013-2014)? The solar track is something that the software calculates from the epw means local time (clock time) file or something that you set additionally (e.g. UCT+1) Is it possible to create epw file without daylight saving time changes +1, -1 ? solar tracks. For example in elements software (bigladder) there are many columns that i do not know (cosine, zenith etc.). Is it a good idea to use an existent epw has solar position data? What for a city and just copy paste these columns or is the relationship time and solar position for Denmark. I use Designbuilder soft. thanksit possible to leave them empty.
