Issue description
I was trying to get the minimum date, so I tried pd.Timestamp.min.normalize()
before realizing that would be out of range, but what's weird is that it overflows without warning:
>>> pd.Timestamp.min
Timestamp('1677-09-21 00:12:43.145224193')
>>> pd.Timestamp.min.normalize()
Timestamp('2262-04-11 23:34:33.709551616')
For reference:
>>> pd.Timestamp.max
Timestamp('2262-04-11 23:47:16.854775807')
Compare that to .floor('D')
, which I thought would be equivalent, but it raises:
>>> pd.Timestamp.min.floor('D')
OverflowError: value too large
The above exception was the direct cause of the following exception:
OutOfBoundsDatetime: Cannot round 1677-09-21 00:12:43.145224193 to freq=<Day> without overflow
as well as .round('D')
(same error).
Sidenote: What I really wanted was .ceil('D')
, which gets the first whole day:
>>> pd.Timestamp.min.ceil('D')
Timestamp('1677-09-22 00:00:00')
