When Notes generates a .ics attachment for a repeating event, it supplies TIMEZONE information for STANDARD and DAYLIGHT, with four parameters for each
example…
BEGIN:STANDARD
DTSTART:19501029T020000
TZOFFSETFROM:+0300
TZOFFSETTO:+0200
RRULE:FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=10
END:STANDARD
BEGIN:DAYLIGHT
DTSTART:19500326T020000
TZOFFSETFROM:+0200
TZOFFSETTO:+0300
RRULE:FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=3
END:DAYLIGHT
Basically, DTSTART is a translation of the RRULE line, which in the DAYLIGHT example above is saying “DST ends at 02:00 AM on the last Sunday in March”. DTSTART translates that for 1950 to March 26. I want to translate it to this year. Has anyone done this - save me a lot of work
