I can see this wouldn't necessarily be an issue with a roster that is kept up to date, but on my beta board, it's become easily noticeable.

Basically the Last Online column is showing relative results based on when it was last updated, rather than relative to current date and time.

An example:

This is known. It's silly. Zanix wrote it, so he gets to defend or change it.

Yeah, this is how I wrote it
Relative to the last memberslist upload time

I suppose we could make an option for relative vs real time

Relative is fine, as long as it's relative to now, rather than when it was uploaded.

It is relative to when the guild list was updated, not 'now'

When Is 'now' if WoWRoster is traveling at the speed of light?

Cheers folks.
