EPW files for locations with Winter Time

There are a few locations where, rather than setting clocks forward for Daylight Saving Time in the summer, the clocks are set back for Winter Time in the winter. What is the convention for the EPW file time zone flag in these cases?

I recently used an EPW file for Dublin, Ireland, and found that it lists the GMT offset as 0, when the standard (summer) time in Ireland is actually GMT+1. This breaks compatibility with time zone aware system libraries (e.g. Python's tzinfo). Is there any advice on how to correct for this?
