According to the PVsyst website: "The Time Zone is the difference between the local Legal time, and the UTC or GMT". Does this mean we have to change the time zone based on daylight savings? Ireland is GMT 0 in standard time but GMT+1 in daylight-saving or summer time. Projects in Ireland are automatically assigned Time zone 1 for some reason, is this just a bug? Also, if I import met data based on either Time zone 1 or 0 then I get different results for the diffuse irradiation - why is this? This then changes the transposition gain.
