Several small functions to extract information from POSIXct indexes.

hms(x)
doy(x)
dom(x)
dst(x)
truncDay(x)

`x`	A `POSIXct` vector.

doy and dom provide the (numeric) day of year and day of month, respectively.

hms gives the numeric value

hour(x)+minute(x)/60+second(x)/3600

dst is +1 if the Daylight Savings Time flag is in force, zero if not, -1 if unknown (DateTimeClasses).

truncDay truncates the POSIXct object towards the day.
