Unless you do recurrent scheduling. In that case it's important to understand that you schedule in a particular timezone. Both because the relationship between local time an UTC changes throughout the year with DST changes and because evaluating an expression like "Thursdays at 03:00" might evaluate differently if you first move the time to UTC (say 22:00) and then check if it's a Thursday (no, it's only Wednesday still, but in 24 hours it'll be time).
