a hardcoded timestamp does not contain milli- or nanoseconds in any format

[vitalz]

Expected behavior

Timestamp should have nanoseconds by default or it should be possible to customise timestamp.

Actual behavior

There are only seconds on a time value. For example there is a log line:

2021-11-06T18:47:14+0300 info

Steps to reproduce

1. Just use StreamLogHandler.standardOutput at LoggingSystem.bootstrap

There is minimal reproducer code

        LoggingSystem.bootstrap{ label in
            var logHandler = StreamLogHandler.standardOutput(label: " org.example.myproject." + label)
            logHandler.logLevel = Logger.Level.debug
            return logHandler
        }
