Thanks for finding this. Behavior is less than optimal and logical, I think.
I have updated the development branch to reflect this documentation:

Accepts the following options:

4.77.2.1. adjust
----------------

If you wish to temporarily adjust the time for display purposes, you
can pass an adjust parameter with the number of hours (plus or minus).

        [time]%c[/time]
        [time adjust="-3"]%c[/time]

Will display:

 Mon 01 Jan 2001 11:29:03 AM EST
 Mon 01 Jan 2001 08:29:03 AM EST

If the number ends in zero and has 3 digits or more, it is assumed
that the number is in timezone format (i.e +500) the local time or
from GMT:

        [time]%c[/time]
        [time adjust="-330"]%c[/time]
        [time adjust="-300"]%c[/time]

Will display:

 Mon 01 Jan 2001 11:29:03 AM EST
 Mon 01 Jan 2001 07:59:03 AM EST
 Mon 01 Jan 2001 08:29:03 AM EST

If you want to force the number to be just a number of hours, add the
hours parameter:

        [time]%c[/time]
        [time adjust="100" hours=1]%c[/time]

Will display:

 Mon 01 Jan 2001 11:29:03 AM EST
 Fri 05 Jan 2001 15:29:03 PM EST

If adjust is an Interchange time duration with a suffix of sec, min,
hrs, days, or weeks, that will be used.

        [time]%c[/time]
        [time adjust="2 days"]%c[/time]

Will display:
