[StGit] import --mail/--mbox question

Hi,

I've been wondering this for quite some time, now try to sort out.

---

Question: when importing Mozilla Thunderbird mails (eml or mbox), the
imported patch always have committer's date in git log, not submitter's
date.  However, if importing the same mails with git am, we could see
submitter's date in git log.

Is this intentionally-designed log management of StGit? I would expect the submitter's date & locale is kept when importing patches from e-mails.

Reproducible: Always

Steps to Reproduce:

1. Prepare eml or mbox file.

  [Thunderbird eml file]
   - Select a mail,
   - File -> Save as -> File, 
   - Format -> Mail files

  [mbox file]
   - use add-ons, such as ImportExportTools(MboxImport)
   - extract directly from profile/ dir

2. Import eml/mbox file with --mail/--mbox option

  $ stg import --mail [eml file]
  $ stg import --mbox [mbox file]

3. Check git log

Example:

  Mbox header (this mbox contains one patch)
