issue #1160 fix

[adamborowski]

If we play with timestamps, we have to leave range bounds integers

Thanks for submitting a PR!

Looking like your patch unfortunately breaks zoom for non-date axes.

I'll look for a better solution. This bug is most likely a side-effect of #1078

[adamborowski]

Yes, we can check if ax.type === 'date' then round the range

@adamborowski @alexcjohnson I think 683d38a would be the most robust way to fix this issue.

@adamborowski to make sure your work is rewarded, I'll apply the above commit on top of your d7de2ae commit, add a few tests and make another PR. Thanks very much for your efforts 🍻
