- * This implementation of mktime is lifted straight from the NetBSD (BSD 4.4)
- * version. I modified it slightly to divorce it from the internals of the
- * ctime library. Thus this version can't use details of the internal
- * timezone state file to figure out strange unnormalized struct tm values,
- * as might result from someone doing date math on the tm struct then passing
- * it to mktime.
- *
- * It just does as well as it can at normalizing the tm input, then does a
- * binary search of the time space using the system's localtime() function.
- *
- * The original binary search was defective in that it didn't consider the
- * setting of tm_isdst when comparing tm values, causing the search to be
- * flubbed for times near the dst/standard time changeover. The original
- * code seems to make up for this by grubbing through the timezone info
- * whenever the binary search barfed. Since I don't have that luxury in
- * portable code, I have to take care of tm_isdst in the comparison routine.
- * This requires knowing how many minutes offset dst is from standard time.
- *
- * So, if you live somewhere in the world where dst is not 60 minutes offset,
- * and your vendor doesn't supply mktime(), you'll have to edit this variable
- * by hand. Sorry about that.
