# 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. | |

# The 'fetch-depth' option ensures that a sufficient number of commits are retrieved (250) | |
# to allow the "git rev-parse" command used below to accurately reference a commit based | |
# on time. | |
# This mitigates potential warnings that occur when there aren't enough commits fetched. | |
# We assume no more than 250 commits are made in a single day. | |
