Note that with recent change (see #541 ), the parameter window for datesearch (only) is restricted to maximum 3 hours. Test should reflect this, and this threshold should be documented in the API.

Yes, simple test fails because it is now in days, not minutes - it is easy to fix. The second one is trickier - now the API does not provide an error message, but just crops the window to 3 hours if it is larger than that. Is it correct behaviour, or we should return the error in this case instead?..

[JulienPeloton]

Fixed in #557
