Time is a semantic category that indicates when a given event occurs. It may be expressed by attributes or by relations.

The values for the attribute time are the following: {{#tree:id=time|openlevels=0|root=Time|

absolute time
- @past: at a time before the moment of utterance
- @present: at the moment of utterance
- @future: at a time after the moment of utterance
- @recent: close to the moment of utterance
- @remote: remote from the moment of utterance
relative time
- @anterior: before some other time other than the time of utterance
- @posterior: after some other time other than the time of utterance

}}

The UNL representation indicates the time rather than the grammatical tense of a form.: There is no simple one-to-one relationship between tense forms and time. In English, for instance, the present (grammatical tense) may be used to represent the future (time); I’m going home tomorrow = go.@future.@recent (and not go.@present)
@present is used to indicate an action at the present, and not habits, routines and statements: I'm in Frankfurt. = @present; I always come to school by cycle. = no time information; The sun sets in the Occident. = no time information
Time values may be combined.: I'm going home tomorrow = go.@future.@recent; I had been there = @past.@anterior

Time may be expressed by the following relations: {{#tree:id=rtime|openlevels=0|root=Time|

}}
