<div>As a point of interest, the spec actually says <a href="https://tools.ietf.org/html/rfc5545#section-3.8.5.3">the behaviour in this case is undefined</a>:<br></div>

<div> The "DTSTART" property<br></div>
<div> value SHOULD be synchronized with the recurrence rule, if<br></div>
<div> specified. The recurrence set generated with a "DTSTART" property<br></div>
<div> value not synchronized with the recurrence rule is undefined.<br></div>
