You don't know the "exact" realtime, but the "nearest minute". Quite simply, when you don't know something (a precise factor), you don't make it up. In this case, you can only list those ACARS, in no particular order, by minute with what information the CMC provided (0210, 0211, 0212..) and assume the time range boundaries for each to be sent.
Hence, you can't have a direct relation with any particular "second" of the real time scale :
- if an ACARS was CMC stamped at 0210 and stamp recieved at 0210:26, all you know is that it could have been triggered between 0209:31 (the nearest minute) and 0210:20 (as you will allow about 6 seconds for processing). If the same was recieved at 0211:31, it would be meaningless to look outside the 0209:31-0210:30 window in order to understand what caused it (in this case, there is certainly no relation with events past 0210:31 even if it was recieved one minute later).
