> This an UI improvement for OLAP jobs.
> OLAP queries are generally small queries which will finish at the seconds or milliseconds, but currently the time precision displayed is second level and not enough for OLAP queries. Millisecond part of time is very important for users and developers, to see accurate time, for performance measurement and optimization. The displayed time includes job duration, task duration, task start time, end time and so on.
> It would be nice to improve this for better OLAP user experience.
