A brand-new release of anytime is now on CRAN following the three earlier releases since mid-September. anytime aims to convert anything in integer, numeric, character, factor, ordered, ... format to POSIXct (or Date) objects -- and does so without requiring a format string. See the anytime page for a few examples.
With release 0.0.4, we add two nice new features. First,

anytime(as.numeric(Sys.time()) also works, effectively adding another input type. We also have squashed an issue reported by the 'undefined behaviour' sanitizer, and the widened the test for when we try to deploy the gettz package get missing timezone information.
A quick example of the new features:
anydate(c(NA, NaN, Inf, as.numeric(as.POSIXct("2016-09-01 10:11:12"))))  NA NA NA "2016-09-01"
