Without an absolute frame of reference how are scientist assigning a time age of the Universe?

No, it isnt. Time depends on the velocity you are travelling

If you are referring to the universe - and not our local time on earth -
There is no "universal time" reference. There is no universal reference of position, velocity or time.
Any and all objects moving at a constant velocity can be a legitimate reference for determining the characteristics of any other reference.
Strange, but true.

Only by definition. 'Universal Time' (or UCT or GMT or Zulu) all refer to Greenwich Mean Time as measured at the British Royal Observatory in Greenwich, England. It is accepted as the 'universal' time standard used by scientists all around the Earth. But there's nothing 'absolute' or 'magic' about it. It's just the standard to which everyone has agreed to reference their measurements.
