[enhancement] Add microseconds to unity8.log prefix

[Daniel van Vugt]

Please add microseconds to the logging prefix used in unity8.log (and more?). They are often useful for debugging and would make things look more consistent with Mir. For example, I just saw this in a user's bug report:

We could certainly make the date/time formats the same...

Unfortunately, I think this isn't possible with Qt: http://doc.qt.io/qt-5/qtglobal.html#qSetMessagePattern

According to http://doc.qt.io/qt-5/qdatetime.html#toString , the highest precision QDateTime can output is milliseconds

It appears you're right. Not possible to fix.
