Examples

tt <- times(c("12:13:14", "15:46:17"))
trunc(tt, "minutes")
#> [1] 12:13:00 15:46:00
trunc(tt, "min")
#> [1] 12:13:00 15:46:00
trunc(tt, times("00:01:00"))
#> [1] 12:13:00 15:46:00
trunc(tt, "00:01:00")
#> [1] 12:13:00 15:46:00
trunc(tt, 1/(24*60))
#> [1] 12:13:00 15:46:00

tt2 <- structure(c(3.0, 3.1, 3.5, 3.9), class = "times")
trunc(tt2, "day")
#> Time in days:
#> [1] 3 3 3 3
trunc(tt2)
#> Time in days:
#> [1] 3 3 3 3
