无法使用请求从网页表格中抓取不同事件的开头

Question

我一直在尝试使用请求模块从该网页的表格中抓取事件时间。 我已经成功地从那里抓取了事件的时间戳，但不知道如何将它们转换为秒或分钟。

下图显示了我想从该表中捕获的事件的开始。

这就是我尝试过的方式：

for item in res.json()['data']['assetEvents']['edges']:
    event_time = item['node']['eventTimestamp']
    print(event_time)

目前的 output 是这样的：

2022-01-06T15:11:05.010779
2022-01-06T14:58:44
2022-01-06T14:53:07.718379
2022-01-06T14:53:07.775447

预期 output：

1 minute ago
1 minute ago
2 minutes ago
2 minutes ago
