English Wikipedia has an article on:eternalismWikipedia
(philosophy) The view that time resembles space and thus past and future events are in some sense coexistent.
The Sarvāstivāda system extended this realism across time, effectively positing a type of eternalism with regards to time, hence the name of their school means "the view that everything exists". Source: Internet
This contrasts with eternalism (all time: present, past and future, is real) and the growing block theory (the present and the past are real, but the future is not). Source: Internet
