    strptimeDate(x, format = whichFormat(x), tz = "")

### Arguments

`charvec` | a character string or vector of dates and times.
`format` | the format specification of the input character vector.
`tz` | a character with the the location of the financial center named as `"continent/city"`, or short `"city"`.
`zone` | the time zone or financial center where the data were recorded.
`x` | a character string or vector of dates and times.
`FinCenter` | a character with the the location of the financial center named as "continent/city".

### Value

returns an object of class `timeDate`.

### Examples

    ## timeDate -

       # 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
