2201 /* All currently known variants of WIN32 operating systems (Windows 95/98,
2202 * WinNT 3.x, 4.0, 5.0) have a nasty bug in the OS kernel concerning
2203 * conversions between UTC and local time: In the time conversion functions
2204 * of the Win32 API, the timezone offset (including seasonal daylight saving
2205 * shift) between UTC and local time evaluation is erratically based on the
2206 * current system time. The correct evaluation must determine the offset
2207 * value as it {was/is/will be} for the actual time to be converted.
2208 *
2209 * Some versions of MS C runtime lib's stat() returns utc time-stamps so
2210 * that localtime(timestamp) corresponds to the (potentially false) local
2211 * time shown by the OS' system programs (Explorer, command shell dir, etc.)
2212 * The RSXNT port follows the same strategy, but fails to recognize the
2213 * access-time attribute.
2214 *
2215 * For the NTFS file system (and other filesystems that store time-stamps
2216 * as UTC values), this results in st_mtime (, st_{c|a}time) fields which
2217 * are not stable but vary according to the seasonal change of "daylight
2218 * saving time in effect / not in effect".
2219 *
2220 * Other C runtime libs (CygWin, or the CRT DLLs supplied with Win95/NT
2221 * return the unix-time equivalent of the UTC FILETIME values as got back
2222 * from the Win32 API call. This time, return values from NTFS are correct
2223 * whereas utimes from files on (V)FAT volumes vary according to the DST
2224 * switches.
2225 *
2226 * To achieve timestamp consistency of UTC (UT extra field) values in
2227 * Zip archives, the Info-ZIP programs require work-around code for
2228 * proper time handling in stat() (and other time handling routines).
2229 */
