Fair points :) As a general note, the time.h isn't doing what I need really (and neither do the current SG time classes). I'm leaving the current code as is, until I decide how I really want to handle time. It's quite likely it will be based on the boost classes, since they are portable, and explicitly handle time zones and many other complex issues. The only problem will be store the values in the property tree. Regards, James ------------------------------------------------------------------------------ Come build with us!
