For 2 ships in space to coordinate a meeting at a specific time, they would first have to agree on a measurement standard and a tool to use to measure it that would behave consistently and change at the same rate for both of them.
They would also need to synchronise at some point prior to setting the appointment.
So many watches, So little time...

Good analogy, this also makes sense with earth ships. However, if lets say ship (B) was from another galaxy, different inhabited planet, and the meeting was to take place at a certain time between the two galaxies, how would this be calculated?
