BlitzMax has the command: CurrentDate$()
Which I found to be pretty much useless if you wanted to actually *use* it for anything.
Spent a while looking for a good library that would do everything I wanted, rather than having to hand-craft all the calculations myself - cuz I don't like re-inventing the wheel all the time.
The boost datetime lib pretty much does everything *I* would want a datetime module to do, so I am very happy with it.
I also included 74 language translations of months and weekdays incase anyone would need that kind of thing. (Yes, they are in a format that would require my locale and libxml module to use, but one can always pull the data out of the xml in another way if they so desire. But again, I just use the tools I have at hand to make the job easier - no point having all these modules if I don't use them ;-)
For some simple datetime stuff, my module is likely to be overkill (no, really!), but for serious work, there's currently nothing else as capable in BlitzMax, as far as I know.
