the cherry orchard make alot of references and allusion to time and time passing. What does the emphasis on time mean?

The emphasis on time is especially important in the context of the passing of the old and the coming in of the new. The old regime has passed, the new life is here, and many parts of the old time are gone. Over time, we forget; we do not remember the good and we often forget that there was a past at all. It is sad that we lose our connection to the past.
