Package: snmp
Version: 5.4.3~dfsg-2.8+deb7u1
Severity: minor

Dear Maintainer,

/usr/bin/traptoemail contains this line:
$message->datasend("Date: ".strftime("%a, %e %b %Y %X %z", localtime())."\n");
Unfortunately %a, %b, %X are all locale dependents.

Let's see what does 'date' with different LANG settings. ('date' also
uses strftime().)

$ LANG=C date +'%a, %e %b %Y %X %z'
Fri, 15 May 2015 15:12:07 +0200            <--- correct
$ LANG=hu_HU date +'%a, %e %b %Y %X %z'
p, 15 máj 2015 15.12.17 +0200              <--- incorrect
$ LANG=en_US date +'%a, %e %b %Y %X %z'
Fri, 15 May 2015 03:12:26 PM +0200         <--- incorrect

Section 3.3 of RFC 5322 specifies format of Date header in mails.
The rules are quite rigid.
I think only the "C" locale guarantees the RFC conform date.
I suggest to insert an
$ENV{LANG} = 'C';
assignment at the very beginning of the script.
