When Does "Gargoyles: Bad Guys" (2007) Take Place?
"Gargoyles: Bad Guys" #1 "Redemption" Chapter One "Strangers" through the final collection with unpublished issues is a supervillain comic-book written by Greg Weisman that first released November 28th, 2007. So when is "Bad Guys" set?
It takes place in the year:
We know this because in all six parts Dingo and Matrix have clearly already joined forces as they determined they would after first meeting near the conclusion of "Gargoyles" season two (1995), which ends in 1996 AD. So the start of the series must be during or after 1996 AD.

1996? AD - 1997? AD
We know this because in all six parts Dingo and Matrix have clearly already joined forces as they determined they would after first meeting near the conclusion of "Gargoyles" season two (1995), which ends in 1996 AD. So the start of the series must be during or after 1996 AD.
Additionally, there are multiple flashbacks labeled with time-setting textboxes that read "TWO MONTHS AGO..." or "TWO WEEKS AGO..." or "FIVE DAYS AGO..." so they are ahead of the main action.
More specifically, during issue #4 "Redemption" Chapter Four "Louse", depicts New York City's New Year's Eve celebration in Times Square held annually in December into January so at this point it crosses over into the next year.
What would have been issues #5 "Strangled" and #6 "Losers" were only published in the collected edition, making them a graphic novella.
