I still advise you not to use this solution. time() is a system call on many operating systems, and so it can be a heavier operation than you'd think. Best to avoid it unless it's needed (on FreeBSD it seems to add about 15% overhead to localtime(), for instance).

I agree. Converting to Argument Clinic should not cause a performance regression. Please don't add new calls to time() for the sake of making code more generic.

A better choice would be to write a converter function in C, then use a custom converter that called it. Nikolaus: Is that something you're comfortable doing?

As for why you're getting that exception, it definitely looks like a bug in Argument Clinic. I spotted another bug that would have bitten you while I was looking for this one, so I've opened bugs on both issues, and put you on the nosy list for them.

According to the issue tracker, " rmsr" has only ever filed one issue.
I just fixed (and closed) it.
