    <p><strong>Question:</strong> Is there a way to tell <code>git send-email</code> to honor <code>git format-patch</code> dates? Better still, is there way to not regard the mail date and commit date as distinct?</p> <p><strong>Observations:</strong> this is my observation about treating dates for which I have not found way to alter</p> <ol> <li>Patches created with <code>git format-patch</code> have the commit date recorded as <code>Date:</code> header.</li> <li>When using <code>git send-email</code> to send the patches, the commit date is changed to the moment of sending</li> <li>When applying the commits with <code>git am</code>, the date as in <code>Date:</code> header of the received email is used.</li> </ol> <p><strong>Partial work-around:</strong> By using a wrapper script for <code>git send-email</code>, it is possible to extract the commit date from the patch and use <code>faketime</code> or similar method to force the <code>git send-email</code> to obey the commit date. This brings two problems, however:</p> <ol> <li>Because the mail date and commit date are collapsed to one (which I regard as conceptual defect), the mail will appear in the inbox in wrong time which is inconvenient.</li> <li>I can only easily apply this method to sending one patch, not a series of patches, if I want them to appear in the same mail thread. Okay, of course I can enable SMTP debugging (<code>git send-email --smtp-debug=1</code>) and extract the <code>Message-Id</code> from the output. But then it start to look like I need to start rewriting the threading options that are already implemented in <code>git send-email</code>...</li> </ol> <p>Note that if <code>git send-email</code> would honor the commit dates recorded by <code>git format-patch</code> then I could use cover letter (<code>git send-email --cover-letter</code>) to deal with the problem number 1, relying on the threading support of the <code>git send-email</code> and MUAs.</p> <p><strong>Bonus Question:</strong> I really would like to see the original commit (implementation) dates in the applied patches for record (series of patches merged in one commit would tell the time of incorporating to the published branch). Is my thinking somehow misguided in wanting this? <em>Is there some deeper thinking in treating the email date and commit date as one?</em> This to me is analogous to pushing local changes to some public branch - the dates are kept.</p> <p><strong>P.S.</strong> There is no tags <code>git-send-email</code> and <code>git-format-patch</code> which I would like to use (reputation will not allow creating them).</p>

    2. CO@VonC - thanks for the link! Very weird that different people have different behaviors for their `git send-email`. The mail list post seems to be about `git am` which is too late phase to fix anything (that's what got patched anyway).

    3. COIs there any chance that two different git versions are involved here? What's yours?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
