Thanks for getting back to me so quickly. 

Given that this is generated by syslog-ng itself, how would I then get syslog-ng to generate this info?  I saw that there is some code in logmsg.c that will do this if stamp->frac_present is true.  So, how does this flag get set to being true?  The self->date->str in log_msg_parse() also appears to determine whether there are fractional seconds available.
