You can use difftime : 你可以使用difftime ：
a <- strptime("23:14:01",format = "%H:%M:%S")
b <- strptime("00:02:01",format = "%H:%M:%S")
difftime(a,b, units = "mins")
# Time difference of 1392 mins
difftime_res_2 <- 1440 - difftime_res # In case the times are from following days
difftime_res_2
# Time difference of 48 mins
