Subject: fixes for log timestamps (#304)

* add GetTimeSinceProcessStart returning time since process start. implemented using https://github.com/maxliani/GetTimeSinceProcessStart/tree/main
* fix fractions when using epoch mode. Previously it would show the fraction from the absolute time stamp and not relative to epoch
* used GetTimeSinceProcessStart to offset the epoch so that it represents the process spawn time
