x |
a vector of POSIXt, numeric or character objects |

further arguments to be passed to specific methods (see above). |
tz |
a time zone name (default: time zone of the POSIXt object |
origin |
a Date object, or something which can be coerced by

format argument for character methods. When supplied parsing is
performed by |
a vector of Date objects corresponding to x
.
These are drop in replacements for as.Date()
and as.POSIXct()
, with a few
tweaks to make them work more intuitively.
as_date()
ignores the timezone attribute, resulting in
a more intuitive conversion (see examples)
Both functions provide a default origin argument for numeric vectors.
as_datetime()
defaults to using UTC.
