Kai: I believe chain mail, as heavy armor, takes 10 minutes to don, so yes that would be time consuming. Pawetha is taking 1 minute to don light armour, so it's 4 extra minutes to get into your mail. Grabbing your sword and shield doesn't 'take time'. I'd also allow you to partially don you armor, taking 5 minutes and receiving the benefits of a chain shirt (13 + Dex mod... which I think your stats reflect actually, so you have a chain shirt not chain mail).
If you indeed have a chain shirt, then donning time is 5 minutes. If you have chain mail, it's 10 minutes but I'll allow you the benefits of a chain shirt with only 5 minutes of effort. If you have chain mail, I'll also allow the benefits of padded armor (11 + dex mod) for 1 minute (as no set of heavy armour doesn't include a padded shirt underneath it all).
