Every line is one title: id plus name, durationInHours 0 means permanent, anything else expires after that many hours (168 = one week, used for ChampionshipWinner and RatedTop1-3). Granting is done by achievements and military ranks via rewardTitle, this file only declares the title.
<Titles>
  <Title id="1" name="Developer" durationInHours="0" />
  <Title id="28" name="ChampionshipWinner" durationInHours="168" />
  <Title id="31" name="RatedTop1" durationInHours="168" />
  <Title id="83" name="Football" durationInHours="0" />
  <Title id="84" name="HungerGames" durationInHours="0" />
</Titles>
Event localhost: set every durationInHours to 0 so nothing expires. Do not renumber ids; rewards reference them by id.
Additional Notes: 

Granting is via achievements.xml rewardTitle and aux MilitaryRank.
