[bug #34744] [NSDate timeIntervalSinceDate:nil] throws an exception

[julian]

Follow-up Comment #2, bug #34744 (project gnustep):

i'm not sure here as well.

throwing an exception sounds like the saner thing to do.

on the other hand, this difference increases the porting effort from cocoa,
e.g. in my case.

i mainly opened the bug to make you aware of the difference.

apple's documentation doesn't explicitly say they return NaN when the input is
nil, but it also doesn't say that the method throws, and since, AFAIK, all
throwing methods are documented, it is implicitly documented that it doesn't
throw ;-)

i can open a bug with apple that they should document that they return nil,
but given my experience with opening bugs with them i expect them to act
somewhere between 5 years from now and never.
