timeDate {timeDate} | R Documentation |
Create a 'timeDate' object from scratch using a character vector.
timeDate(charvec, format = NULL, zone = "", FinCenter = "")
strptimeDate(x, format = whichFormat(x), tz = "")
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 |
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". |
returns an object of class 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")

## 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
