Sort order of Same day time slots is lost

Patch like proposed above.

I did not test with exceptional day or seasons.

Thanks,
patch needs some rework.
It is possible that endhours or starthours are empty (value NULL), in that case the sorting is not executd, due to the isset().

In #3 johnv states:

It is possible that endhours or starthours are empty (value NULL), in that case the sorting is not executd, due to the isset()

If endhours or starthours are empty (value NULL) we cannot compare the values - so we cannot sort by 'em.
Patch #2 than falls back to the behaviour without the patch - i.e. same day means "equal" (return 0).

We could implement something like not null value is greater than NULL or something similar.

Or what am I not getting?

The patch is committed, without the isset() checks.

Automatically closed - issue fixed for 2 weeks with no activity.

Please check #3416914-14: Sort order of same day slots incorrect in row (widget) and column (formatter) → .
That patch basically reverts this one. The hours of one day should be unsorted. It is the user's responsibility.
The change will be in current dev version or in version 8.x-1.13
