%{t} is meant to be a URL argument. I expect ISPs to use exp= to set up
web pages for users who need to "phone home" using SASL SMTP. Those web
pages need all the clues they can get. Knowing the time of a problem
scenario is useful because that lets you say "we had a minor DNS
misconfiguration on Saturday morning, please disregard any bounces you
saw and resend the message, it should go through now".
web pages can then display the localtime()d version.
