Configurable Slack time/date formats

Users in organizations with a configured Slack connection can now configure any of the formats above to be used in personal notifications or messages sent to configured channels in Slack.

  • To override Slack’s default format and use your preferred time format for personal notifications, enable the Slack Time Format toggle on your profile page.
  • To configure a preferred time format for a specific channel, send a time_format set <format-name> message to On-Call Optimizer in the channel.

The slack documentation has been updated with further information and configuration details.

Bugfixes and minor changes

  • Prevented destinations that are up to date from sending “reminders” of their up to date status every 7 days.
  • Improved mobile display and layout responsiveness on the swap response screen for schedules containing members with long names.
  • Optimized rendering performance for schedules with many shifts per month displayed on the calendar.
  • Eliminated incorrect override removed notifications that were being generated for overrides that had actually been exported by On-Call Optimizer, but were exported more than a week ago!
  • Fixed an issue causing shifts that are eligible for swapping to not be listed on the swap response page in cases where different time zones are configured between the swap requester, responder and the schedule.
