Drop this into your project. The expression is the one above.

Spring @Scheduled

@Scheduled(cron = "0 */30 * * * *", zone = "UTC")
public void runJob() {
    // ...
}

application.properties

app.job.cron=0 */30 * * * *
# @Scheduled(cron = "${app.job.cron}")

The Spring fields, in order: second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).

The expression has six fields, so */15 in the minutes position still needs a leading 0 for seconds, or the job fires every second of those minutes.
Spring evaluates in the server time zone by default. Add zone = "UTC" (or any ZoneId) to @Scheduled to make it explicit.

If you want "every half hour starting at :10" you need a list like 10,40, not */30, which always lands on :00 and :30.
