Comment 13 for bug 1641875

# VERIFICATION FOR X&Y

After running the following script (repro.sh), the log shows the LDAP resolution is rescheduled:

#!/bin/bash

change_time() {
        sudo systemctl stop systemd-timesyncd
        HOUR=$(date +%H)
        MIN=$(date +%M)
        NEW=$((10#$HOUR - 1))

        sudo date --set "${NEW}:${MIN}"
        echo "Setting time to ${NEW}:${MIN}"
}

sudo systemctl restart sssd
sleep 20
change_time
