Using "disable" as a noun
It seems the noun derived from the verb "disable" is disablement.
"Disablement time" or "disablement duration" sounds a little awkward to me though. "Disable time" sounds better, and also gives much more Google hits. But would you say that is correct or acceptable? How about "disabling time"?
(Or is my question misworded; are you even supposed to use a noun in such context?)
Background: I'm trying to decide the name of a setting that specifies the time for which a certain software functionality is disabled.
Solution 1:
Both Merriam-Webster and Wiktionary only mention disable as a verb.
After seeing the background you provided, I would go with idle time (898,000 Google hits vs 36,000 hits for disable time). The Business Dictionary suggests waiting time as an alternative.
Edit: as pointed out in the comments by Kosmonaut and Bruno, yet another alternative would be disabled time or perhaps time disabled (with a participle rather than the infinitive form).
