我得到了下面的html，我想得到event_timestamp的文本

<tr id="eventRowId_454169" event_attr_id="25" event_timestamp="2022-07-19 12:30:00" onclick="javascript:changeEventDisplay(454169, this, 'overview');">
                <td class="first left time">15:30</td>
                <td class="flagCur"> USD</td>                   <td class="sentiment" title="High Volatility Expected"><i class="newSiteIconsSprite grayFullBullishIcon middle"></i><i class="newSiteIconsSprite grayFullBullishIcon middle"></i><i class="newSiteIconsSprite grayFullBullishIcon middle"></i></td>                <td class="left event">Building Permits (Jun)</td>

                                                            </tr>

下面是我的代码

Time = row.tr['event_timestamp']

我得到 None ，我可以改变什么来获得时间？
