$abbr
[, int $gmtOffset = -1
[, int $isdst = -1
]] ) : string
abbrTime zone abbreviation.
gmtOffset
Offset from GMT in seconds. Defaults to -1 which means that first found
time zone corresponding to abbr is returned.
Otherwise exact offset is searched and only if not found then the first
time zone with any offset is returned.
isdst
Daylight saving time indicator. Defaults to -1, which means that
whether the time zone has daylight saving or not is not taken into
consideration when searching. If this is set to 1, then the
gmtOffset is assumed to be an offset with
daylight saving in effect; if 0, then gmtOffset
is assumed to be an offset without daylight saving in effect. If
abbr doesn't exist then the time zone is
searched solely by the gmtOffset and
isdst.
