ZF-9870: Zend_Log - line 303 - Allow us to define timestamp
As mentioned in summary, the timestamp value is hardcoded as date('c'). For some of us we use a specific time stamp pattern for our logging to allow for easy parsing via pre-defined regexes. It would be nice if we could override the value before being passed to $event var.
For now I have created a child class which extends Zend_Log and copied the Log() function contents to the child class to override, kinda messy but gets us by.
