I wrote about a related issue several years back, starting with

 	https://dovecot.org/list/dovecot/2012-March/134706.html

I'm not sure how I got over this and got usable "date.saved" cache values,
and why it stopped working.  Maybe I need to set something like

 	mail_always_cache_fields = date.saved
 	mail_cache_fields = date.saved

to force date.saved to be cached.

You may or may not have the same problem I do -- your timestamps actually
differ, whereas mine are all the same.
