Delay somewhere in a possibly busy system. "application" looked at its 
watch. Decided the time was 20:56:10, started building a string, then 
(some time later) pushed that string into a socket. Some time later, 
svlogd pulled the string from the socket, looked at its watch, started 
building a string, then wrote the string into the file.

Such discrepancy is inevitable, but won't necessarily be noticeable.
