strftime error output

[ricoeo]

I am dealing with a time series data, with timestamp as index. While dealing with the index, I find this error.

This is my datetransfer function:
from datetime import datetime
def datetransfer(time):
return datetime.fromtimestamp(time).strftime("%A, %B %d, %Y %H:%M:%S")
There is a missing in 2:00:00 but it is so obvious the adjacent time data only differ in 1 hour.

Is this a daylight savings time issue?

This looks suspiciously like a DST transition. datetime.fromtimestamp is documented to convert to the local time and return a naive datetime object.

Yeah I want to convert it to local time because I need to find a complete natural week data(from Monday to Sunday).

OHHH. thanks I think this is a reasonable explanation.

Did 02:00 on March 29, 2020 exist in your timezone?

Thanks for your help. I think this is just as @ericvsmith said. I found out when I try to group by the same date and there are some duplicates.
