Time Bubble
From Tardis Wiki, the free Doctor Who reference
A time bubble occurred when an individual met his past or future self under certain circumstances. A bubble resulted in time being frozen save for the individual who caused it. The bubble would quickly deteriorate and normal time would resume.
The Eighth Doctor caused time bubbles when he was visiting his past incarnations to reclaim lost memories. (PROSE: The Eight Doctors)
The Time Lords captured the King Yrcanos in a time bubble on Thoros Beta, in order to release him at the right time for an attack to the laboratory of Crozier - whose work they wanted to be wiped out. (TV: Mindwarp
