Dates and times of attendance markings are listed in the future

[ricarcya]

I am testing the library with the MA300-BT fingerprint device. Everything has worked well, until the moment of recovering the employee's assistance that appear with dates of several months or years in the future.

To Reproduce Steps to reproduce the behavior:

1. date of test jue jun 18 19:21:36 -04 2020 (utc -4)
2. Use ./test_machine.py -a 192.168.0.191 -f -v -r
3. See error ATT 1: uid: 38, user_id: 38 t: 2026-06-06 12:35:12, s:8 p:39 ATT 2: uid: 38, user_id: 38 t: 2026-06-06 21:58:24, s:8 p:39 ATT 3: uid: 38, user_id: 38 t: 2026-06-07 03:35:28, s:8 p:39 ATT 4: uid: 38, user_id: 38 t: 2026-06-07 15:06:40, s:8 p:39

Expected behavior list of attendances with correct date/time test_machine_output.txt

THX! .....its works

change the line 1563 of base.py to

uid, status, punch, timestamp = unpack('<HBB4s', attendance_data.ljust(8, b'\x00')[:8])

before change ATT 1: uid: 38, user_id: 38 t: 2026-06-06 12:35:12, s:8 p:39

after change ATT 1: uid: 38, user_id: 38 t: 2020-06-17 10:58:21, s:8 p:0

same device MA300-BT
