   # Character Vector Strings:
   dts = c("1989-09-28", "2001-01-15", "2004-08-30", "1990-02-09")
   tms = c(  "23:12:55",   "10:34:02",   "08:30:00",   "11:18:23")

   dts; tms

   t1 <- timeDate(dts, format = "%Y-%m-%d", FinCenter = "GMT" )
   t1
   
   stopifnot(identical(t1, timeDate(dts, FinC = "GMT"))) # auto-format
   
   timeDate(dts, format = "%Y-%m-%d", FinCenter = "Europe/Zurich")
   
   timeDate(paste(dts, tms), format = "%Y-%m-%d %H:%M:%S",
        zone = "GMT", FinCenter = "GMT")
   
   timeDate(paste(dts, tms), 
        zone = "Europe/Zurich", FinCenter = "Europe/Zurich")
   
   timeDate(paste(dts, tms), format = "%Y-%m-%d %H:%M:%S",
        zone = "GMT", FinCenter = "Europe/Zurich")

   ## Non Standard Format:
   timeDate(paste(20:31, "03.2005", sep="."), format = "%d.%m.%Y")

   ## Note, ISO and American Formats are Auto-Detected:
   timeDate("2004-12-31", FinCenter = "GMT")
   timeDate("12/11/2004", FinCenter = "GMT")
   timeDate("1/31/2004") # auto-detect American format

   ## From POSIX?t, and using NAs
   ## lsec <- as.POSIXlt(.leap.seconds) ; lsec[c(2,4:6)] <- NA
   ## timeDate(lsec)

   ## dtms <- paste(dts,tms)
   ## dtms[2:3] <- NA
   ## timeDate(dtms, FinCenter = "Europe/Zurich") # but in GMT
