This original version of "The Young Offenders" is actually set in a "flashback" version of 2007, although both Jock and Conor are 15. The same entire set of characters, with new additions, would re-appear in the TV series version of the BBC Three/RTE/Vico Film re-boot, but some of their personalities, circumstances and situations would be slightly revised, and re-used.
The film takes place in 2007.
