I have two pd.Timestamp objects: t1 = pd.Timestamp(2022-11-02 10:44:22.700000) t2 = pd.TImestamp(2022-11-02 10:44:22.760000) Now I want to get the timedelta for those two values. If I do it like this: t2 – t1 I get Timedelta(‘0 days 00:00:00.060000’), which is the expected behaviour, but If I do: t1 – t2 I get Timedelta(‘-1 days +23:59:59.940000’),… Read More Pandas timedelta subtraction returns different values when operands are swapped
