I have this for a schedule:

1. Every minute, 7am-7pm, Monday-Friday

• 7-19 * * 1-5

Hudson gives me a warning:
Do you really mean "every minute" when you say "* 7-19 * * 1-5"? Perhaps you
meant "0 7-19 * * 1-5"

A * in the first column means "every minute" – and the suggestion would be mean
once per hour.
