8-, 10-, 12- and 14-digit formats are understood, e.g: 20150721 to 20150721000000.
Integers will be converted to character before parsing. All incoming dates will be interpreted
in the specified <code>timezone</code> ("UTC" by default).
If <code>datetime</code> is a <code>POSIXct</code> it will be returned unmodified.
