/* Precompute the offset from GMT on systems where it's not

|

|
||||
Note: This offset is normalized to be independent of daylight
|
||||
savings time; if the calculation happens to be done in a
|
||||
time/place where a daylight savings adjustment is in effect,
|
||||
the returned offset has the same value that it would have
|
||||
in the same location if daylight savings were not in effect.
|
||||
The reason for this is that the returned offset can be
|
||||
applied to a past or future timestamp in explode_time(),
|
||||
so the DST adjustment obtained from the current time won't
|
||||
necessarily be applicable.
|
||||
|
||||
mktime() is the inverse of localtime(); so, presumably,
|
||||
passing in a struct tm made by gmtime() let's us calculate
|
||||
the true GMT offset. However, there's a catch: if daylight
|
||||
savings is in effect, gmtime()will set the tm_isdst field
|
||||
and confuse mktime() into returning a time that's offset
|
||||
by one hour. In that case, we must adjust the calculated GMT

offset.
