Why do many functions that calculate duration only use timestamp_key instead of reserving start_timestamp and timestamp_key at the same time.

I wonder if pm4py didn't consider the start and end time in the log at the same time, because many functions that calculate the duration only use timestamp_key instead of reserving start_timestamp and timestamp_key at the same time.

Dear @DAAworld

Most process mining algorithms consider naturally events with just a timestamp. Very few use the start/end timestamp information.

In pm4py, some methods offer support for start/end timestamps, however, the support is not systematic and limited to few algorithms.

Yes, I noticed, so, in some needed methods, I can only modify it myself. Have you considered making some changes in the future?

As long term plan yes, but that also depends on the development of process mining algorithms that use the lifecycle information in a more effective way
