We do something fairly strange on our commands that might be useful here. We treat the string argument for a duration or timer as having 3 potential signs: "-", "+", and "@". Dash and plus *always* mean relative-to-now. @ always means absolute time.
Any given option or argument documents whether its *default sign* is -,+, or @. For expirations, we usually say that the default is "+". So "-expiry 5" is 5 seconds from now, while "-expiry @5" expired a long time ago. And it makes parsing a timer or duration a standard operation throughout our code. Unfortunately, it's in our C++ stuff, so not really suitable for the Naviserver core.

But you're right, it's ugly when you just want to specify an offset from now such as +3 seconds. I've changed it in CVS so that small -timeout and -expiry times are treated as offsets from now, and large values are treated as absolute times in the future. ------------------------------------------------------------------------ - Using Tomcat but need to do more?
