'Time' is PIE *deh- (to divide) — time as something sliced into portions. Kin to 'tide.'
The indefinite continued progress of existence and events in the past, present, and future, regarded as a whole.
From Old English 'tīma' (time, period, season, occasion), from Proto-Germanic *tīmô, derived from PIE *deh₂i- or *dī- (to divide, cut up, apportion). Time was conceived in the proto-language as something divisible — a continuum cut into measurable portions. The same PIE root *deh₂i- feeds Greek 'daíomai' (I divide, distribute) and possibly 'daimōn' (a divine spirit, originally a 'divider' of fates). In Proto-Germanic the root produced *tīmô (timed portion) and also underlies Old Norse
