as_date(x, ...) as_datetime(x, ...) ## S4 method for signature 'POSIXt' as_date(x, tz = NULL) ## S4 method for signature 'numeric' as_date(x, origin = lubridate::origin) ## S4 method for signature 'POSIXt' as_datetime(x, tz = "UTC") ## S4 method for signature 'numeric' as_datetime(x, origin = lubridate::origin, tz = "UTC") ## S4 method for signature 'ANY' as_datetime(x, tz = "UTC")
x |

origin |
a Date object, or something which can be coerced by

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.
dt_utc <- ymd_hms("2010-08-03 00:50:50") dt_europe <- ymd_hms("2010-08-03 00:50:50", tz="Europe/London") c(as_date(dt_utc), as.Date(dt_utc)) c(as_date(dt_europe), as.Date(dt_europe)) ## need not suply origin as_date(10)
