Unwanted character in time field

[Andy Melton]

I have recently installed a Free Radius server to collect accounting output from a Cisco AS5350.  Up until today, it was working fine, but at 4:00 pst yesterday, the timestamps from the accounting record are prepended by an *.   I’m not sure if this was caused by the AS5350, which I’m guessing it is, but has anyone seen this and do you know how to strip off that *?   Thanks for your help.
