+# I coined "IST/IDT" circa 1988.  Until then there were three
+# different abbreviations in use:
+#
+# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
+# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
+# EEST Eastern Europe Standard Time [used by almost everyone else]
+#
+# Since timezones should be called by country and not capital cities,
+# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
+# EEST was equally unacceptable.  Since "zonal" was not compatible with
+# any other timezone abbreviation, I felt that 'IST' was the way to go
+# and, indeed, it has received almost universal acceptance in timezone
+# settings in Israeli computers.

+# In any case, I am happy to share timezone abbreviations with India,
