Standalone_edc/local_dc need to coordinate better on when standalone_edc needs to have its writes done
Standalone_edc currently triggers off of the clock, writing data at 16Hz boundaries. Local_dc triggers off of when the IOP is done. There are off of different clocks.
The current fix is to change the delay that standalone_edc uses to time its writes. The code can fire early or wait and go later.
This might mean we need to restore the ability to read time from the iop (or at least sync with the iop on startup).
