Daylight Saving Time / Summer Time changes approaching

[L. David Baron]

Time changes for summer time / daylight saving time in the northern
hemisphere are beginning **this weekend**, with the change on Sunday
(March 12) to Daylight Saving Time in most of the United States and
Canada and in some nearby areas, which means clocks in those areas
move forward one hour. Next week, meetings whose times are fixed to
US time will start one hour earlier for those in time zones that are
not changing (and then change again if and when local time changes
for the attendee).

It may be helpful to note the time zone change when scheduling and
announcing meetings. Starting Sunday (March 12), California time is
designated as PDT, Pacific Daylight Time, UTC-07:00, or UTC-7. This
means that 11:00 PDT is 18:00 UTC.

A few of the largest time changes this season are:

Roughly the southern half of Brazil (GO, DF, MG, ES, RJ, SP, PR,
SC, RS, MS, MT) moved backwards one hour on Sunday, February 19
(2017-02-19).

Most of the US and Canada and some surrounding areas move forward
one hour on Sunday, March 12 (2017-03-12). (The large areas that
don't change are Hawaii, most of Arizona, and most of
Saskatchewan.)

Europe (except Iceland, Russia, Belarus, Armenia, Azerbaijan,
Georgia, Crimea, Donetsk, Luhansk, and Northern Cyprus) moves
forward one hour on Sunday, March 26 (2017-03-26).

New Zealand and South and southeastern Australia move backwards
one hour on Sunday, April 2 (2017-04-02).

Most of México (except Sonora, Quintana Roo, and areas along the
US border) moves forward one hour on Sunday, April 2 (2017-04-02).

Before I built a wall I'd ask to know
What I was walling in or walling out,
And to whom I was like to give offense.
