+# and indicates that standard time was adopted effective noon, January
+# 13, 1896 (page 218), that in "1933, the Legislature decreed daylight
+# saving for the period between the last Sunday of each April and the
+# last Sunday of each September, but less than a month later repealed the
+# act," (page 220), that year-round daylight saving time was in effect
+# from 1942-02-09 to 1945-09-30 (page 221, with no time of day given for
+# when clocks changed) and that clocks were changed by 30 minutes
+# effective the second Sunday of June, 1947 (page 219, with no time of
+# day given for when clocks changed). A footnote for the 1933 changes
+# cites Session Laws of Hawaii 1933, "Act. 90 (approved 26 Apr. 1933)
+# and Act 163 (approved 21 May 1933)."

+# From Arthur David Olson (2011-01-19):
+# The following is from "Laws of the Territory of Hawaii Passed by the
+# Seventeenth Legislature: Regular Session 1933," available (as of
+# 2011-01-19) at American University's Pence Law Library. Page 85: "Act
+# 90...At 2 o'clock ante meridian of the last Sunday in April of each
+# year, the standard time of this Territory shall be advanced one
+# hour...This Act shall take effect upon its approval. Approved this 26th
+# day of April, A. D. 1933. LAWRENCE M JUDD, Governor of the Territory of
+# Hawaii." Page 172: "Act 163...Act 90 of the Session Laws of 1933 is
+# hereby repealed...This Act shall take effect upon its approval, upon
+# which date the standard time of this Territory shall be restored to
+# that existing immediately prior to the taking effect of said Act 90.
+# Approved this 21st day of May, A. D. 1933. LAWRENCE M. JUDD, Governor
+# of the Territory of Hawaii."
+#
+# Note that 1933-05-21 was a Sunday.
+# We're left to guess the time of day when Act 163 was approved; guess noon.
