Time deltas. #. Timedeltas are differences in times, expressed in difference units, e.g. days, hours, minutes, seconds. They can be both positive and negative. Timedelta is a subclass of datetime.timedelta, and behaves in a similar manner, but allows compatibility with np.timedelta64 types as well as a host of custom representation, parsing Recommendation. It is recommended to convert as follows: deltatime.astype("timedelta64[ms]").astype("int64")/1000 Problem of times.astype("timedelta64[ms]").astype(int). The data type timedelta64 stores data as a 64-bit integer. The astyp(int) method will convert data into a 32-bit integer. So there is a chance that the conversion will fail, as demonstrated below: This method converts an argument from a recognized timedelta format / value into a Timedelta type. Parameters: arg str, timedelta, list-like or Series. The data to be converted to timedelta. Changed in version 2.0: Strings with units 'M', 'Y' and 'y' do not represent unambiguous timedelta values and will raise an exception. In Python 3.2 or higher, you can divide two timedelta s to give a float. This is useful if you need the value to be in units other than seconds. time_d_min = time_d / datetime.timedelta(minutes=1) time_d_ms = time_d / datetime.timedelta(milliseconds=1) edited Sep 17, 2019 at 23:11. answered Jan 28, 2014 at 22:57. dan04.
