-s reload does not update logfiles time, v1.5.6

A -s reload works as documented, however while the logfiles are being
written to, the logfiles keep their last (before -s) time/date. Is this
a
known issue?

After a simple restart the logfiles are time updated as normal.

It’s a documented “issue” …

use -s reopen (or kill -USR1) to reopen the logfiles.
