For example, this quote is used for 8:19:
> I had arranged to meet the Occupational Health Officer at 10:30. I took the train from Watford Junction at 8.19 and arrived at London Euston seven minutes late, at 8.49.|The Terrible Privacy of Maxwell Sim|Jonathan Coe
If the location aware option were enabled, it would give that to me at 1:19, not 8:19, because I'm in PDT (UTC-0700).
(Well, 1:19 if London is not also on daylight savings time. If they are, then I'd get it at 0:19. This is one of the reasons it is probably more work than it is worth. You'd not only have to have the location information for the quotes, you'd also have to deal with the rules for daylight savings time in multiple locations. This would be a pain in the ass).
