.. and is "clearly" defined by the POSIX standard as follows:

 "A positive or 0 value for tm_isdst shall cause mktime() to presume
initially that Daylight Savings Time, respectively, is or is not in

cause mktime() to attempt to determine whether Daylight Savings Time
is in effect for the specified time." [1]
