Pandas datetime interval
Webpandas supports converting integer or float epoch times to Timestamp and DatetimeIndex. The default unit is nanoseconds, since that is how Timestamp objects are stored internally. However, epochs are often stored in another unit which can be specified. These are computed from the starting point specified by the origin parameter. >>> WebParameters startstr or datetime-like, optional Left bound for generating dates. endstr or datetime-like, optional Right bound for generating dates. periodsint, optional Number of periods to generate. freqstr or DateOffset, default ‘D’ Frequency strings can have … DataFrame - pandas.date_range — pandas 2.0.0 documentation
