No, a timeout report is just an additional hint for the decoder that a specific amount of time has passed since the last pulse _now_.

When timeout reports are enabled the sequence must be: <pulse> <timeout> <space> <pulse> where <timeout> is optional. lircd will not work when you leave out the space. It must know the exact time between the pulses. Some hardware generates timeout reports that are too short to distinguish between spaces that are so short that the next sequence can be interpreted as a repeat or longer spaces which indicate that this is a new key press.
