Maybe "30" is something else, not a time-based thing. Exactly 30, at that.
Just from context, I think Q is pointing to the McCain "situation" in some way.
Flynn is involved in some way, some how. The Sara Carter story talked about Flynn and why he got cut loose by Obama for bucking him on the "Al Queda on the run" fakery.
Then when he joined the Trump campaign, the derps had to take him out, which they did, because they didn't want him close to Trump.
Flynn is important and related somehow to Clinton Foundation/McCain Foundation dark foreign money flow.
Is this bigger than we know?
Betcha it is.
Can't put my finger on it, though. :(

Here are two thoughts as to why.
"30 has been traditionally used by journalists to indicate the end of a story. There are many theories about how the usage came into being,[1]e.g. from that number's use in the 92 Code of telegraphic shorthand to signify the end of a transmission in the American Civil War era.[2] In another theory, the "-30-" originated when stories were written in longhand; X marked the end of a sentence, XX the end of a paragraph, and XXX meant the end of a story. The Roman numerals XXX translate to 30."
