Subject: [PATCH] fix export timezone and calendar month title

- Export now uses time.Now().In(loc) for year/month so users in
  positive UTC offsets get the correct month
- Export month title for Jalali/Hijri now correctly converts the
  first day of the Gregorian month to the target calendar instead
  of using the Gregorian month index to look up target month names
