He could. But if Mahz did that, then Phantomlink probably wouldn't have observed the timestamp reporting 24 hours, unless Mahz is doing something more complicated.

Ok. 23.5 hours rounds up to 24 hours. But, as you mentioned, 23.5 hours is not a day. Hence a possible reason why you're seeing both 24 hours and 1 day in the timestamp.
I'll delve into the guild code to see if I can find what's going on.

EDIT: I found it. He's using a little plugin for it called timeago.
[code]      var words = seconds < 45 && substitute($l.seconds, Math.round(seconds)) ||
        seconds < 90 && substitute($l.minute, 1) ||
        minutes < 45 && substitute($l.minutes, Math.round(minutes)) ||
        minutes < 90 && substitute($l.hour, 1) ||
        hours < 24 && substitute($l.hours, Math.round(hours)) ||
        hours < 42 && substitute($l.day, 1) ||
        days < 30 && substitute($l.days, Math.round(days)) ||
        days < 45 && substitute($l.month, 1) ||
        days < 365 && substitute($l.months, Math.round(days / 30)) ||
        years < 1.5 && substitute($l.year, 1) ||
        substitute($l.years, Math.round(years));[/code]

Key point is that, if time is [i]less than[/i] 24 hours, it displays time in hours, [i]rounded to the nearest[/i] hour. If time is equal to or greater than 24 hours, it will display time in days (or greater units)
