Try search
for this forum. Lot of example how to make timestamp file and use it.

This code give example howto make -30 min timestamp.
day=$(date '+%Y%m%d')
hh=$(date '+%H')
mm=$(date '+%M')
(( mm < 0 )) && ((mm=60+mm)) && ((hh-=1))
(( hh < 0 )) && hh=0 && mm=0 # or you need day-1 also ...

((mm < 10 )) && mm="0$mm"
((hh < 10 )) && hh="0$hh"
# now use touch -m to set some tmpfile and use find

If your version of find does not support the mmin option,
you can use Perl:

find . -type f -exec perl -le'
  (30/1440) > -M and print for @ARGV
  ' {} +
