Subject Re: Question regarding the technical details of a log rollover
Date Wed, 21 May 2014 17:56:40 GMT
I'm pretty sure the answer is that it must be actively logging, and that
does in fact make sense since I doubt you are trying to actively parse log
files.  So I guess the question is how do I set the daily rollover to
happen at a certain hour, rather than at midnight?

Thanks
