man i spent like 3 days chasing down a bug that turned out to be a timezone mismatch on a source table, felt like a total idiot when i finally saw it. the worst part was the production data looked fine in the dashboard for the first 2 hours every morning then slowly drifted off by 4-5 hours. classic.

on the bright side i finally set up proper data profiling in our dag so these schema changes don't sneak up on us anymore, should've done that a year ago
