... don't forget that Date('now') returns the UT1 date, not the local (as in
Wall Clock/Calendar) date ... date('now', 'localtime') gives the local date in
accordance with the timezone where your computer thinks it is located and
should always be accurate for 'now' but maybe not a few years in the past on
Operating Systems that do not contain/use a full set of UT1 -> localtime
(timezone) conversion rules (such as Windows).

The fact that there's a Highway to Hell but only a Stairway to Heaven says a
lot about anticipated traffic volume.
