I have configured the logrotate in my conf file, and odoo seems to correctly cut the logs into daily files.

But the last modification date doesn't match with the file date... For exemple : 

Mar 28 05:33 odoo.log.2017-03-23

Mar 27 11:46 odoo.log.2017-03-24

Mar 27 08:08 odoo.log.2017-03-25

Mar 28 05:14 odoo.log.2017-03-26

Any explication? Am I missing something?
