Between 2005 and 2012, Israeli daylight savings time (Asia/Jerusalem) ended on the Hebrew calendar, which is lunisolar: the rule was that DST ended on the Saturday before Yom Kippur (the 10th of Tishrei). (It started on the Gregorian calendar, on the Friday before April 2nd.) The law was changed in 2013, but this still seems like something you could try modeling with RSCALE, either for the historical period or for a proleptic version of the 2005 rules. -- Jonathan Lennox lennox@cs.columbia.edu
