quartz based schedule issues

If I try to create a schedule which needs to run for every 3599 seconds.

*/3599 * * * * *

It triggers it every 1 min, doesn't throw an error.

But this would do well if it is in the bounds of the second.

Is this expected. Is there a way around to achieve the above schedule?

I have a custom executor and using parser to parse and validate schedule. Using Next to identify next schedule trigger time.
