// @evo-todo window.performance does not exist on node.js, but there is a module performance-now. Maybe use it
/**
* Returns a high resolution timestamp in microseconds if supported by the environment, otherwise in milliseconds.
* The timestamp is based on 01/01/1970 00:00:00 (UNIX epoch) as float with microsecond precision or
* with millisecond precision, if high resolution timestamps are not available.
* The fractional part of the timestamp represents fractions of a millisecond.
* Converting to a Date is possible by using require(["sap/base/util/now"], function(now){new Date(now());}
