Get time in milliseconds

Is there a way to get time in milliseconds, or something more accurate than just seconds?
/system clock print or :system clock get time will only give time to the nearest second, which isn’t good enough if I’m trying to time events that take less than a second to complete.e.g. a fetch.

At the moment RouterOS does not account milliseconds, and there are no too much setups where second is too big value for time.
