How to standardize and communicate one's age across interstellar colonies?

The concept of "age" on Earth is based on the number of revolutions the planet has completed since one's birth. In a setting where interstellar colonies exists, of even in a setting where multiple colonies are established on planets which all have different revolution times around their sun, how would one speak about his age to an inhabitant of another planet? For example, a 32 year old human on planet Earth would be equivalent to ~380 years for a Jovian.

What standard measures could be applied to beings to easily understand the age of the other without requiring constant conversion into Earth revolutions? At the moment, my ideas are either:

1. Physical and mental assessment test; or
2. Length of telomeres

Would like comments or suggestions. Thanks
