CodePudding user response：

import pandas as pd
pd.to_datetime("2022-12-25 13:38:22.561470", format='%Y-%m-%d %H:%M:%S.%f').timestamp()

CodePudding user response：

You can use datetime module to convert your string to datetime object and then get your timestamp :

from datetime import datetime


with open("packet.txt", "r") as f:
    packet_time = f.readline()

print(datetime.strptime(packet_time, "%Y-%m-%d %H:%M:%S.%f").timestamp())

Text file content :

2022-12-25 13:38:22.561470

Output :

1671971902.56147
