made modifications to time

Current setup: 
Use server time (PT) unless client explicitly sets the timestamp

Problems with setup:
Clients potentially set wacky times. These are potentially damgaing to loads. 

Proposed solution:
Make time always be server time. If client sent time move to client_time field. client_time is the unix epoch timestamp.

Steps needed:
Add client_time to all tables
make/deploy code change in spade to set timestamp in the way described
i don't think this is necessary here - you might want to legitimately override IP. for example, with minute_broadcast, you'd want it to report the IP of the broadcaster, not the rails server
