Description

If the value is a TIME, delay for that period. If the value is a DATE (with time), wait until then. If the value is an INTEGER or DECIMAL, wait that number of seconds. If the value is a PORT, wait for an event from that port. If a block is specified, wait for any of the times or ports to occur.
