Tomasz Janiszewski commented on MESOS-6790:
-------------------------------------------

I created first commit 
https://github.com/janisz/mesos/commit/0256557e89360bffe902b56ebf7e478cc34e8876#diff-28ebad5255c4c1a70b4abf35651198fdR7825
 but I have no idea when start time should be updated? I changed updateStatus 
and if status is != STAGING and task already has not start time or update is 
earlier then start time gets updated with status timestamp. Is this good way or 
maybe it should be handle differently.

> Hi
> When task has enabled Mesos healthcheck start time in UI can show wrong
> time. This happens because UI assumes that first status is task started
> [0]. This is not always true because Mesos keeps only recent tasks statuses
> [1] so when healthcheck updates tasks status it can override task start
> time displayed in webui.
