Incorrect timestamp logging in gssftpd (krb5-workstation)

[Philip Prindeville]

I found a situation (fairly common, actually) under which gssftpd
generates incorrect timestamps as a result of chroot()ing and losing
access to the /etc/localtime file (it surprises me that localtime(3)
doesn't cache the file's contents in glibc... oh, well).

I came up with a work-around for this which is fairly simple.

Can someone else code review it?  And if the Kerberos folks
(krbdev) don't want to include the fix (I sent it to them, but didn't
hear back) what's the criteria for it being included in the Redhat/
Fedora packaging instead?

Here's the bug report (fix included):
