It happens if you use as.POSIXlt() or strptime() directly.
as.POSIXlt()
strptime()
data.frame(time='2014/01/01 10:10:10') %>% dplyr::mutate(time=as.POSIXlt(time)) # Error: wrong result size (11), expected 1 or 1
You get the same error wrong result size (11) regardless of the length of the data.frame The expected output would be the same as using plyr::mutate()
wrong result size (11)
plyr::mutate()
str(data.frame(time='2014/01/01 10:10:10') %>% plyr::mutate(time=as.POSIXlt(time))) # 'data.frame': 1 obs. of 1 variable: # $ time: POSIXlt, format: "2014-01-01 10:10:10"
This error occurs in both dplyr version 0.3.0.1 on CRAN and latest github versions.

I don't think we can support POSIXlt in data frames - it really is a list of 11 components. You're much better off with POSIXct.
POSIXlt
Sorry, something went wrong.
We could, with some work. I think what I'm going to do is use POSIXlt as an advanced example for #650 if it still does make sense when I tackle it.
Fair enough, I didn't realize how POSIXlt was implemented. POSIXct works fine for my use case as well.
POSIXct

I've made this explicit:
> data.frame(time='2014/01/01 10:10:10') %>% dplyr::mutate(time=as.POSIXlt(time)) Erreur : `mutate` does not support `POSIXlt` results
Perhaps not as good as actually supporting POSIXlt, but less it'd be more work.
