now

The time of this decision, epoch milliseconds, from the node's clock: the commit time its events are recorded at, which a sourcing function reads back as EventStream.commitTime. A decision computes a deadline or an expiry from it, not from the system clock, so a test sets it: the test DSL's time starts at its start and moves with advanceTime. A decision decided again, after a version conflict, reads the clock anew.
