How to use the python pypff library to find the start and end time of an event in the outlook calendar (*.pst)

Question

How to use the python pypff library to find the start and end time of an event in the outlook calendar (*.pst)?

Using my recursive function, I get access to calendar events as messages, and then I get all the attributes.

In the list of attributes with type datetime I get the time of creation, modification, etc. - I do not need them.

one message <pypff.message object at 0x0000021CC3698150>
    --  one_attr=client_submit_time   2024-01-23 02:25:38.495000 <class 'datetime.datetime'>
    --  one_attr=creation_time        2024-01-23 02:25:18.160000 <class 'datetime.datetime'>
    --  one_attr=delivery_time        2024-01-23 02:25:38.495000 <class 'datetime.datetime'>
    --  one_attr=modification_time    2024-01-23 09:34:04.661000 <class 'datetime.datetime'>

Then, through record_sets, I get 8 more entries with datetime type, which have different entry_types.

entries record_set <pypff.record_set object at 0x0000021CC36080D0>
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 2, 25, 38, 495000) one_entry.entry_type=57
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 2, 25, 38, 495000) one_entry.entry_type=3590
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 2, 25, 18, 160000) one_entry.entry_type=12295
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 9, 34, 4, 661000) one_entry.entry_type=12296
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 6, 30) one_entry.entry_type=32772
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 24, 9, 0) one_entry.entry_type=32773
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 6, 30) one_entry.entry_type=32774
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 24, 9, 0) one_entry.entry_type=32775
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 2, 25, 38, 495000) one_entry.entry_type=32882
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 6, 30) one_entry.entry_type=32888
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(4501, 1, 1, 0, 0) one_entry.entry_type=32890
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 23, 6, 30) one_entry.entry_type=32942
   * one_entry.value_type=64 one_entry.data_as_datetime=datetime.datetime(2024, 1, 24, 9, 0) one_entry.entry_type=32943

This is how the event is produced in Outlook itself:

def getID(f, level = 0, findAttr=None, ix=None):
    methods = dir(f)
    getAttr(f, skip_staff=True, findAttr=findAttr, skipEnum=False)
    enumses = []
    if 'record_sets' in methods:
        enumses.append(f.record_sets)
    if 'sub_folders' in methods:
        enumses.append(f.sub_folders)
    if 'sub_items' in methods:
        enumses.append(f.sub_items)
    if 'sub_messages' in methods:
        enumses.append(f.sub_messages)
    if 'entries' in methods:
        enumses.append(f.entries)
    if ('sub_messages' in methods) and (findAttr is not None):
        enumses.append(f.sub_messages)


    for idx0, one in enumerate(enumses):
        for idx, one2 in enumerate(one):
            getID(one2, findAttr=findAttr, level = level+1)

How to understand which entry_type corresponds to the beginning and end of an event in the calendar?

Or is there any other way to get the subject, Start, End of each event?
