[Python] The program stops when it encounters a time jump

I wrote a program for filter in my pacman log for the package changes after 21:00 hrs but not even reads all the log file.

import re

def filter(filename, date, outFilename):
with open(filename, 'r') as infile, open(outFilename, 'w') as outfile:
for line in infile:
match = re.match(r'^\[(\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2})\+\d{4}\]', line)
if match:
current_time = match.group(1)
print(current_time)
if current_time >= date:
outfile.write(line)

filter('/var/log/pacman.log', '2025-01-02T21:00:00', 'filteredRegister.txt')


the line 'print(current_time)' is for debug. the program stops after 2024-12-24T20:29:34, i think because the hour in the log's hour changes suddenlu to 2024-12-24T15:54:02 for a change in the timezone. Anyone can help me? PD: forgive my horrible english please.
