Can I schedule tasks for a certain time of day?
Yes! This is configurable via the task's subscriptions (available in each task's advanced settings). You'll want to start with one of Mechanic's scheduler events (see All event topics / Mechanic). Then, append a time delay, like one of these options:
mechanic/scheduler/daily+6.hours(runs at 6am)
mechanic/scheduler/monday+20.hours(runs Mondays at 8pm)
mechanic/scheduler/hourly+30.minutes(runs every hour, on the half hour)
