Questions
What is the cron expression for every day at midnight?
0 0 * * *. At 00:00, every day.
Which timezone will it run in?
Crontab on a server uses the server clock (often UTC). In RunLater you pick the timezone on each scheduled request, and daylight saving changes are handled for you.
What if the job fails?
Plain cron does not retry. RunLater retries a failed request (non-2xx or timeout) with exponential backoff, up to 10 attempts, and logs every attempt with the status code and response body.
