[Users] MoL Arrays

[Christian Reisswig]

ok, I have scheduled my RHS functions in global mode.
In the global RHS function I set my RHS source term to an analytically known 
value at some time "cctk_time".

Weirdly, "cctk_time" does not carry the value of the intermediate MoL step for 
my global-mode function. Instead, it is always set to the time that MoL 
reaches after its "n" substeps. Is this behavior intended? To me, this looks 
like a bug since I would expect a proper "cctk_time" in the MoL substeps also 
for global-mode functions.

Thanks for any hints,
Christian
