I had to revert to FB1.5 as the client threw a wobbly and gave me no time to affect a proper fix using the inbuilt date functions and then I forgot about it until now.

Few years ago you said... enough time to find what wrong with UDF or, better, to replace it by new built-in functions.
But you, probably, like to use outdated and not supported (for free) FB 1.5 ;)
