无法以日期格式转换 unix 时间戳

Question

我正在尝试将 unix 时间戳转换为类似 DD/MM/YYYY HH:MM:SS 的日期。由于某种原因，我无法正常工作。你能看看我做错了什么吗，我刚开始使用 Python 3.8.8

import requests, json
import datetime as dt
r = requests.get('https://api1.binance.com/api/v3/ticker/24hr')
jm = json.loads(r.text)
for n in range(len(jm)):
        
        x=(jm[n] ['closeTime'])
        # printing unix timestamp
        print (x)
        # trying to get the date time
        time_val = dt.datetime.fromtimestamp(x)         
        print(time_val)

感谢您的宝贵时间和帮助。谢谢

Answer 1

你得到的时间戳是以毫秒为单位的，你需要把它转换成秒，比如

time_val = dt.datetime.fromtimestamp(x/1000)

Answer 2

那是因为 API 以毫秒为单位给出结果，请尝试：

time_val = dt.datetime.fromtimestamp(x/1000.0)

Answer 3

你应该试试这个：

import requests, json
import datetime as dt
r = requests.get('https://api1.binance.com/api/v3/ticker/24hr')
jm = json.loads(r.text)
for n in range(len(jm)):
        
        x=(jm[n] ['closeTime'])
        # printing unix timestamp
        print (x)
        # trying to get the date time
        time_val = dt.datetime.fromtimestamp(x/1000).strftime('%Y-%m-%d %H:%M:%S')
        print(time_val)

最后几个输出：
