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.
