Dear all,

I am using the ISOdatetime function like this:

test.info$TradeTime = with(test.info, mapply(FUN = ISOdatetime, Year, Month, Day, Hour, Minute, 60, "EST"))


Where Year, Month etc are all numeric.

I think ISOdatetime should return a POSIXct object. However, the result I obtained from the line above is all numeric. Could you please advise? I wish to get POSIXct.

Thank you very much!
