timing at LLO mid station hampered by long cable to IOC
Timing card at mid is in the IOC, but server is still in the corner stations, so the long cable causes a large delay when reading the timing card, resulting in a "time 0" that's in error.
Suggested fix: add parameter to IOP for timing delay. Subtract the timing delay from the received value, so we get the time when requested from the server, not when received by the timing card. We can get a close enough estimate by looking at the delay in the timing system, even though it's a different fiber.
Note, this is a one way delay that will be about 10 microseconds, since the returned time is not added to the value.
