Package: pure-ftpd
Version: 1.0.21-8
Pure-ftpd supports the "SITE UTIME" command, which allows the client to
set the modification time of a file to a particular timestamp, expressed
in UTC.
However, pure-ftpd passes the UTC timestamp directly to the operating
system's utime() function, which is a bug, because utime() requires that
the timestamp be in local time instead of UTC.
The end result is that, for example, if your server is in time zone
US/Pacific, the "SITE UTIME" command sets the file's timestamp 7 hours
ahead of what it should be.
See this page (which was written by someone else) for a confirmation:
http://www.smartftp.com/support/kb/pureftpd-utime-bug-f2615.html
To fix the bug, pure-ftpd needs to convert UTC to local time. The fix is
trivial on Linux: Just replace "mktime()" with "timegm()" in doutime()
of ftpd.c (I've tested this and it works).
