Good call. I’m away from home right now but I’ll send an updated patch tonight.

[PATCH] Add local_date_header option Export this patch

Add an option to convert the date used in the Date header into the local
(sender's) timezone. This is the current behavior and the option
defaults to true. Unsetting this option causes the date in the Date
header to be formatted using the GMT timezone.

Hi Gregory,

I think this is okay.  Just a minor formatting nitpick below:

This option is useful for privacy-sensitive users who may not wish to
divulge their sending timezone.

Mutt puts the curly brakets on separate lines.  You can leave off curly 
brackets for the else if you like.

  if (option (OPTLOCALDATEHEADER))
  {
    l = localtime (&t);
    tz = mutt_local_tz (t);
  }
  else
  {
    l = gmtime (&t);
  }

I made the requested formatting change and I also just initialized `l` 
with gmtime(&t) which removes the `else` branch entirely. Let me know if 
you prefer it the other way and I'll switch it back.

Hi Gregory,

I think it's better to have the else branch.  Most people will leave the 
option set, so performing the gmtime() syscall in advance is a waste 
(albeit a tiny one).
