(aka Temporal Lock)
A Time Lock can be used to prevent a time traveller (with a lower reality quotient) from affecting a time zone or object. Any time an event is observed by a sentient being (whether biological or artificial) that event becomes crystallized in history. The higher the observer's reality quotient, the more crystallized or fixed in history the event becomes. A TARDIS normally has a reality quotient of slightly less then one to reduce its impact in any time zone. However a TARDIS's reality quotient can be boosted so that it can place a Time Lock field on a nearby object to fix it in time. An object (even another TARDIS) under a strong Time Lock is very difficult to dematerialize into the Vortex. It also becomes very hard for any timeship to enter a zone that has been Time Locked. This boost is limited to a reality quotient of 3 for a Type 40. Thus a Type 40 could trap another Type 40 but a later model TARDIS would be able to escape, sending the Type 40 spinning off into the Vortex.
