       Michael,

       Yes the qx command having problems are always involved date
       manipulation like the following:

            qx/date +"START:%d-%b-%Y %H:%M" > $global::lock_file/;

       but not sure if that is what you mean by 'native format'.

       Regards,
       Philip

I don't know.

However - do you use the UseDateTime attribute? I've just had another
error report with memory problems with perl 5.004_04 when using the
UseDateTime attribute (ie retrieving dates in native format).
