| ahh, but I think @kawochen soln fixes the root of the problem. |
Fixes unusual bug with timezone Series subtraction in which single element Series objects containing tz-aware objects would return a timedelta of zero, even though it visually could not be the case. The bug was traced to the conversion of the contained timezones to UTC, in which the method call was somehow returning NaT, even though attempts to replicate that behaviour were unsuccessful. This new method call fixes the issue and is in some ways more intuitive given the comment above the conversions. Closes pandas-devgh-12290.
