as_datetime returns POSIXlt

[adfi]

I ran into a problem when using as_datetime in combination with dplyr::mutate. The latter doesn't accept POSIXlt which was being returned by as_datetime. However looking into the documentation there is no mention of POSIXlt. The documentation states: "These are drop in replacements for as.Date() and as.POSIXct()".

So is the documentation incomplete or should the function be changed?

Example:
library(lubridate)
class(as_datetime("2018-09-05 09:41:31", format="%Y-%m-%d %H:%M:%S"))
[1] "POSIXlt" "POSIXt"

There might have been a reason for that. If not, the output type should be changed indeed. Will have a look.

Minimal reprex illustrating inconsistency:

library(lubridate, warn.conflicts = FALSE)
class(as_datetime("2018-09-05 09:41:31"))
#> [1] "POSIXct" "POSIXt"
class(as_datetime("2018-09-05 09:41:31", format="%Y-%m-%d %H:%M:%S"))
#> [1] "POSIXlt" "POSIXt"
