Locks the local chain to commence a countersigning session. The
PreflightRequestAcceptanceMUST be sent back to the session initiator so that the corresponding entry can be built for everyone to sign. This function MUST be called by every signer in the signing session. It doesn’t matter how, although concurrent remote calls are probably the simplest mechanism to distribute and accept preflight requests before the session times out.
Wrapper function around
CounterSigningSessionTimes. These session times are included in the
PreflightRequestand bound the countersigning session temporally. This function starts the session “now” in the opinion of the session initiator and ends it after
msmilliseconds relative to “now”. The countersigning parties will check these times as part of accepting the preflight request so all system clocks need to be roughly aligned and the ambient network latency must fit comfortably within the session duration.
