This is too difficult for me to understand without
knowing more about your data or what you mean by "this order".
My earlier solution was over-elaborate.
by group, sort : egen maxtime = max(time)
by group : egen mintime = min(time)
gen middletime = floor((mintime + maxtime) / 2)
gen byte select = inrange(time, middletime - 12, middletime + 12)
can be slimmed to
by group (time), sort : gen middletime = floor((time[1] + time[_N]) / 2)
gen byte select = inrange(time, middletime - 12, middletime + 12)
