Absolutely. The time zones supported by DateTime are designed to be 
robust, not only for today but back to 1970.

EST is
(1) ambiguous (there's an EST in both America and Australia)
(2) a 'standard' time (the 's') not a summer or daylight time
     and so the offset wont ever change
(3) historically un-mappable to any 'proper' time zone as they
     keep changing by civil decree in various jurisdictions

Cheers!
