Closes #10609
This adds support for 'Z' in a timestamp string for the
%z
specifier. Normally, the%z
specifier expects an hour-minute format like+HHMM
but strptime and other libraries also accept a single 'Z' here. The following two strings should result in the same timestamp value:"2022-04-07 09:15:00Z" and "2022-04-07 09:15:00+0000"
The
cudf::strings::is_timestamp
andcudf::strings::to_timestamps
have been updated to support this behavior. A gtest was updated to include this as a testcase.
