Hi,

Actually under the 'Level = Incremental' section of the page you linked 
it states:

"The File daemon (Client) decides which files to backup for an 
Incremental backup by comparing start time of the prior Job (Full, 
Differential, or Incremental) against the time each file was last 
"modified" (st_mtime) and the time its attributes were last 
"changed"(st_ctime). If the file was modified or its attributes changed 
on or after this start time, it will then be backed up."

So we were both right almost :)

I've seen Bacula compensate for different clock times on servers a few 
seconds/minutes apart - it logs a line at the top of the job saying it's 
doing so.

However, I've never tried it when the clocks are hours/timezones apart 
so cant say if it'd compensate then.

Cheers,
