| # Daily at 04:00 AM UTC (this corresponds to the time set in CTestConfig.cmake + 1 hour) | |
| # | |
| # This workflow is synchronized with the nightly builds on the Kitware-hosted dashboards, | |
| # which are configured via crontab to trigger daily at 11:00 PM Eastern Time (ET). The conversion | |
| # from ET to UTC depends on whether daylight saving time is in effect: | |
| # | |
| # - During the spring/summer months (typically March to November), Eastern Daylight Time (EDT), | |
| # which is UTC-04:00, is observed. Thus, 11:00 PM EDT corresponds to 03:00 AM UTC. | |
| # - During the autumn/winter months (typically November to March), Eastern Standard Time (EST), | |
| # which is UTC-05:00, is observed. Thus, 11:00 PM EST corresponds to 04:00 AM UTC. | |
| # | |
| # The build jobs are configured to start via the crontab on the Kitware-hosted dashboards at | |
| # 11:00 PM ET, and this workflow is scheduled to run daily at 04:00 AM UTC to ensure it executes | |
| # after the nightly builds have started and completed their source checkout, regardless of daylight | |
| # saving time. | |
| # | |
| # This is important because the preview branch should be updated to reflect the state of the | |
| # repository as of the latest nightly build. | |
