I guess a simple solution would be to define in the spec that date/time types which are not an instant in time will<br>
always use a fixed time zone (eg UTC) for comparison. This would most likely also lead to some confusing border cases<br>
for users, but it would be deterministic.<br></blockquote><div><br></div><div>This shows a misunderstanding of choosing the type you need. If you have LDT, you have a single fixed time zone that you know what is (for instance, a system is only used in a single location), that's what should be used in the server side for comparison. If you have different time zones, you probably need ZDT.</div><div><br></div><div>Regards,</div><div>Michael</div></div></div></div>
