When does cron.daily etc run?

I wanted to know what time of day my cron.daily, cron.weekly, etc. cron jobs where scheduled to run. The answer is in /etc/crontab:

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

Resolved firefox ssl_error_expired_cert_alert

I was getting the error ‘ssl_error_expired_cert_alert’ in Firefox. I checked my client certificate and it hadn’t expired. I checked my CA certificate and it hadn’t expired. It turned out that the problem was that my ca.crl Certificate Revocation List had expired. I fixed that by running jj5-bin empathy-ca-update-crl which says:

echo Updating CRL...
openssl ca -gencrl -config ca.cnf -cert cacert.crt -out ca.crl.pem -crldays 365
if [ "$?" -ne "0" ]; then
  echo Error updating CRL.
  exit 1
fi

echo Exporting CRL to DER format...
openssl crl -in ca.crl.pem -outform DER -out ca.crl.der
if [ "$?" -ne "0" ]; then
  echo Error exporting CRL in DER format.
  exit 1
fi

echo Viewing CRL...
openssl crl -in ca.crl.pem -noout -text
if [ "$?" -ne "0" ]; then
  echo Error viewing CRL.
  exit 1
fi
