CURRENT_DATE and CURRENT_TIME functions disabled?

Anyone knows why these values in "asterix-om/src/main/java/edu/uci/ics/asterix/om/functions/AsterixBuiltinFunctions.java” are false?

addFunction(CURRENT_DATE, ADateTypeComputer.INSTANCE, false);
addFunction(CURRENT_TIME, ATimeTypeComputer.INSTANCE, false);

Thanks,
-heri

Thanks. This means we should not change them to “true” and keep them 
as they are.

Best,

I thought it meant that it was false that they are FUNCTIONS.
(These return different values per call even if given the same params.)

As far as I know, that false means that the function doesn't require any
parameters. If it's true, then we need to provide parameters.

The last parameter of addFunction is called isFunctional. So I think that this means that these functions are not actually functional in the sense that their result is not a consequence of the arguments that are being passed (especially as they don’t get any arguments).

Cheers,
Till
