We convert the complete.date object to POSIXlt:

date.complete2 <- as.POSIXlt(date.complete)

# we can decompose the date object with unclass() function

unclass(data.completo2)

$sec

[1] 10

$min

[1] 57

$hour

[1] 12

$mday

[1] 17

$mon

[1] 9

$year

[1] 115

$wday

[1] 6

$yday

[1] 289

$isdst

[1] 0

attr(,"tzone")

[1] "GMT"
