mminfo savetime query

Hello,

I would like to know why mminfo together with a savetime query no longer seems to work as expected.

Note the following mminfo query. It shows that there are no savesets after December 3rd 2021.

nws:~ # mminfo -q 'volume=XL2586L7, savetime>12/3/21' -avot
6095:mminfo: no matches found for the query

But in fact there are: There are savesets on December 4th 2021, and more.

nws:~ # mminfo -q 'volume=XL2586L7' -avot | head -20
volume type client date time size ssid fl lvl name
XL2586L7 LTO Ultrium-8 home02 12/04/21 00:45:38 184 GB 1806347412 cE full /vol1
...

If for example I invert the filter, it shows those savesets.

nws:~ # mminfo -q 'volume=XL2586L7, savetime<12/3/21' -avot | head -20
volume type client date time size ssid fl lvl name
XL2586L7 LTO Ultrium-8 home02 12/04/21 00:45:38 184 GB 1806347412 cE full /vol1
...

Can you tell why that filter (no longer) works as expected, or not at all?

Thanks
