I don't know if it's a Korean thing or my mom-specific thing but she had very strong opinion about being early. For her 15 minutes early == on time. To reinforce this notion, she would set the house clocks later by some random undetermined minutes. The clocks in her home would all differ slightly so you could never tell what time it actually was unless you looked at your phone but you'd know you're little bit early to things for sure. Good times.
She didn't by chance serve in the military or a civil auxiliary branch, did she?
"Early is on time, on time is late, and late is unacceptable" was drilled into me while doing Civil Air Patrol back in secondary school (high school) and I habitually set all my clocks 5 minutes ahead, still, to this day.
