This is wrong: the dst bit determines whether timestamps are
considered to be daylight-saving time or not. The definition
of the tm_isdst flag does not even mention standard time, and
standard time is not an antonym to daylight-saving time.
In fact, any dictionary tells us that daylight-saving time
is advanced, and not retarded, over the time used otherwise,
and the case of Ireland shows us that standard time may agree
with daylight-saving time.
