[R] seq() problem with chron

I encountered the problem below where the last value in the chron vector created with seq() should have a time of 15:30, but instead has 15:15.  What causes this and how can I make sure that the last value in the chron vector is the same as the "to" value in seq()?

dt1 <- chron("02/20/13", "00:00:00")
dt2 <- chron("07/03/18", "15:30:00")
dt <- seq(from=dt1, to=dt2, by=1/(24*4))
#[1] (07/03/18 15:15:00)
