Returns the microsecond component of each element. This is available only for Series containing timedelta values, which is a result of taking
the difference between two timestamp Series.
Compute the millisecond component of a timestamp column:
>>> feature = catalog.get_feature("CustomerLatestInvoiceTimestamp")
>>> feature_group = fb.FeatureGroup([feature])
>>> feature_group["TimestampMicrosecond"] = feature.dt.microsecond
