That it is EKG data is helpful; assuming that a “Tick” is 3 seconds, taken from Loyola here: http://www.meddean.luc.edu/lumen/meded/medicine/skills/ekg/les1prnt.htm
We can calculate time elapsed; that being said, three thousand Ticks is still only a few hours - so it is like these Tick values you see represent, for example, the time elapsed since the EKG data collection was started - definitely not a date, and probably not even a time (unless this example of data collection was taken at 2.30am).
I’m attaching a workflow which lets you specify either date, or date and time, of the start of the data collection run, and which then produces the absolute date-time based on the Tick values. Attaching a screenshot of the results and workflow as well.
