Fwd: Daylight Saving Time / Summer Time changes approaching

FYI, the DST time change season begins soon, with the US changing this 
weekend.  We should reconsider our telcon time once all of these changes 
have happened, which ends with Australia changing on April 6.

Since our telcons are fixed to UTC, this means next week's (not this 
week's) call in Pacific time will change from 1:30 pm to 12:30 pm.

Time changes for summer time / daylight saving time in the northern
hemisphere are beginning **this weekend**, with the change 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, of course, 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, 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 16
   (2013-02-16).

   Most of the US and Canada and some surrounding areas move forward
   one hour on Sunday, March 9 (2013-03-09).  (The large areas that
   don't change are Hawaii, most of Arizona, and most of
   Saskatchewan.)

   Europe (except Russia, Belarus, Iceland, Armenia, and Georgia)
   moves forward one hour on Sunday, March 30 (2013-03-30).

   New Zealand and South and southeastern Australia move backwards
   one hour on Sunday, April 6 (2013-04-06).

   Most of México (except Sonora and areas along the US border) moves
   forward one hour on Sunday, April 6 (2013-04-06).

              What I was walling in or walling out,
              And to whom I was like to give offense.
