With the base RR3 code (in other words, no hacks): You cannot access date sensitive content without being online There is also a validation for the triggering of events I cannot say with 100% certainty that you are restricted from entering or using these two features once they have triggered if you are offline. I do know that they use your devices time and date to unlock next days goals (SEs and started FBs) and Daily Rewards and Ads.
 * Weekly Time Trial Tournament
 * Online Multiplayer
 * Race Team Challenges
 * Special Events
 * Limited Timed Series
 * Daily Rewards
 * Reset of daily currency ads limit (20 and 170BRL) at 00:00

I would also guess that there is a validation of date and time with EA servers that takes place to make sure that your device time is a valid time somewhere in the world at that time, so that the device isn't set to be a few days ahead or behind the current date, however I am not 100% certain that this validation works. Again, remember I added the caveat that I am describing the normal operating mode of RR3 and what may or may not be possible with hacks or exploits.

Also, your device needs to be on line to collect ads, however, I am not sure of the effect if your device is online and EA's servers are offline.
