From stat().st_mtime to datetime?
提问by Travis Griggs
What is the most idiomatic/efficient way to convert from a modification time retrieved from stat()call to a datetimeobject? I came up with the following (python3):
从stat()调用检索到的修改时间转换为datetime对象的最惯用/最有效的方法是什么？我想出了以下内容（python3）：
from datetime import datetime, timedelta, timezone
from pathlib import Path
path = Path('foo')
path.touch()
statResult = path.stat()
epoch = datetime(1970, 1, 1, tzinfo=timezone.utc)
modified = epoch + timedelta(seconds=statResult.st_mtime)
print('modified', modified)
Seems round a bout, and a bit surprising that I have to hard code the Unix epoch in there. Is there a more direct way?
似乎差不多，有点令人惊讶的是我必须在那里对 Unix 纪元进行硬编码。有没有更直接的方法？

Try datetime.fromtimestamp(statResult.st_mtime)
尝试 datetime.fromtimestamp(statResult.st_mtime)
e.g.
例如
import datetime
mod_timestamp = datetime.datetime.fromtimestamp(path.getmtime(<YOUR_PATH_HERE>))

This works for me if you want a readable string:
如果你想要一个可读的字符串，这对我有用：
import datetime
mtime = path.stat().st_mtime
timestamp_str = datetime.datetime.fromtimestamp(mtime).strftime('%Y-%m-%d-%H:%M')
