Syslog - Different Timezone Causes Un-Deleteable Entries

Issue is caused when a device sends a syslog from a timezone ahead of the observium/syslog capture server. In my case, the server is running at UTC-6 and the device runs at UTC.

The "Recent Syslog Messages" displays the message time as negative. When trying to clear out the entries with housekeeping.php it clears out everything but these entries.
