Re: [Haskell-cafe] Re: TimeDiff to Int?

Thanks, but that doesn't seem to work. I got an answer of -3. I tried it again a minute later and it was still -3. I tried again a minute later and it was -1. It's just after 9am here, so I have no idea what to make of those numbers. I have settled on this code: secondsSinceMidnight :: IO Int secondsSinceMidnight = do zonedTime <- getZonedTime return $ floor $ toRational $ timeOfDayToTime $ localTimeOfDay $ zonedTimeToLocalTime zonedTime On Thu, Nov 13, 2008 at 2:29 AM, Jon Fairbairn wrote:

I had some code using the oldtime package, and want to convert it to use the time package. One of the things I need to do is calculate the number of seconds since midnight. The easy part is getting a TimeDiff result:

You mean DiffTime?

...

utc <- getCurrentTime tz <- getCurrentTimeZone let td = timeOfDayToTime $ localTimeOfDay $ utcToLocalTime tz utc Now td is a TimeDiff representation of the number of seconds since midnight. It prints nicely, but I'm having a heck of a time figuring out how to truncate it to an Int.

You could do something like fromEnum td `div` fromEnum (secondsToDiffTime 1) which says that you are computing a whole number of seconds.
