How to parse this date/time in Java/Kotlin? I have this NMEA timestamp: 120722202122 and I want to parse it. I tried import java.time.LocalDateTime import java.time.format.DateTimeFormatter fun main() { println(LocalDateTime.parse("120722202122", DateTimeFormatter.ofPattern("DDMMyyHHmmss"))) } Playground but I get an Exception: Conflict found: Field MonthOfYear 1 differs from MonthOfYear 7 derived from 2022-01-12 I don't know what the Exception wants to tell...
