Indeed, it's perfectly acceptable, and probably preferable to just give
the Gregorian dates.
If you want to be more exact, you need not only to specify a calendar
from the date and location (including the planet), but also political or
religious power you're abiding to, and even with that, we lack a lot of
information given that a lot of calendars were relative (to the reign of
the current monarch, or the foundation of the local city), and that we
may not have all the information needed to synchronize them.
What would be the birth date of Cochise's great great great grand
father? I mean, assuming you know how many seconds ago he was born, it
was before the Americas went under the political power of European
countries. Each tribe had its own moon names, I don't know if they even
had absolute year counters.
