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