Sometimes when I try to login (to edit a page) here then I can see
the following error message:
Error: OpenID failure: time_bad_sig:
Please note that authorization process successes on OpenID server side.
It occurs both for [getopenid.com](http://www.getopenid.com/)
and [myopenid.com](http://www.myopenid.com/) servers I use.
I'm reporting this, but I'm not sure whether a problem is with your
ikiwiki or my OpenID servers. --[[Paweł|ptecza]]

> The perl openid client module seems

# check age/signature of return_to
my $now = time();
{
my ($sig_time, $sig) = split(/\-/, $self->args("oic.time") || "");
# complain if more than an hour since we sent them off
return $self->_fail("time_expired") if $sig_time < $now - 3600;
also complain if the signature is from the future by more than 30 seconds,
# which compensates for potential clock drift between nodes in a web farm.
return $self->_fail("time_in_future") if $sig_time - 30 > $now;
# and check that the time isn't faked
my $c_secret = $self->_get_consumer_secret($sig_time);
my $good_sig = substr(OpenID::util::hmac_sha1_hex($sig_time, $c_secret), 0, 20);
return $self->_fail("time_bad_sig") unless $sig eq $good_sig;
}

I've had this problem too, but with my track record of reporting OpenID bugs
I thought it best if I held my tongue. I usually experience this the first
time I sign in on any ikiwiki installation of {ikiwiki.kitenet, ikidev,
betacantrips}, and I think re-logging in always works. --Ethan
