Ubuntu時間戳在編程中有多種應用,主要包括以下幾個方面:
import time
current_timestamp = int(time.time())
timestamp1 = int(time.time())
time.sleep(5) # 等待5秒
timestamp2 = int(time.time())
time_difference = timestamp2 - timestamp1
import logging
logging.basicConfig(filename='app.log', level=logging.INFO)
logging.info(f"User logged in at {int(time.time())}")
INSERT INTO events (event_type, timestamp) VALUES ('login', UNIX_TIMESTAMP());
sudo ntpdate pool.ntp.org
cache.set('key', 'value', timeout=3600) # 緩存1小時
user_login_time = int(time.time())
schedule.every().day.at("10:30").do(job_function)
import os
last_modified_time = os.path.getmtime('/path/to/file')
import requests
headers = {'Timestamp': str(int(time.time()))}
response = requests.get('https://api.example.com/data', headers=headers)
import pandas as pd
df['timestamp'] = pd.to_datetime(df['timestamp'], unit='s')
總之,時間戳在編程中的應用非常廣泛,幾乎涉及到所有需要處理時間的場景。合理利用時間戳可以提高程序的可靠性和效率。
