Audit finding B4 — actual bug, LOW-MEDIUM.

Cron check-in durations are computed as currentTimeMillis() - start (wall clock):

• sentry/src/main/java/io/sentry/util/CheckInUtils.java:64
• Same pattern in SentryCheckInAdvice across sentry-spring, sentry-spring-jakarta, and sentry-spring-7.

Cron jobs run long, giving wide exposure to wall-clock steps over the measured interval → wrong or negative durations reported.
