t1 <- seq(from = as.ITime("0:00"), to = as.ITime("0:40"), by = as.ITime("0:06"))
str(t1)
# int [1:7] 0 360 720 1080 1440 1800 2160

# workaround:
t2 <- as.ITime(seq(from = as.ITime("0:00"), to = as.ITime("0:40"), by = as.ITime("0:06")))
str(t2)
# 'ITime' int [1:7] 00:00:00 00:06:00 00:12:00 00:18:00 00:24:00 00:30:00 00:36:00

Just recognized that the same happens with c():

c(as.ITime("0:00"), as.ITime("1:00:00"))
