Everyone can contribute. Help move this issue forward while earning points, leveling up and collecting rewards.

Summary

When you are setting pipeline schedule to run e.g. 7 18 2 4 * which is At 18:07 on day-of-month 2 in April it would instead be scheduled to At 19:00 on day-of-month 2 in April incorrectly interpreting minute value.

Steps to reproduce

  1. Open Pipeline Schedules
  2. Configure pipeline to run at 7 18 2 4 *
  3. Save this value
  4. Check when the pipeline is scheduled to run with hover over value in Next Run column
  5. It will output 2 April 2024 at 19:00:00 CEST

Example Project

What is the current bug behavior?

When the pipeline schedule is set to run at minute other than 0 e.g. 7 18 2 4 * - it will run an hour later in this case at minute 0 or At 19:00 on day-of-month 2 in April

What is the expected correct behavior?

When the pipeline is scheduled to run at minute other than 0 e.g. 7 18 2 4 * it runs At 18:07 on day-of-month 2 in April
