Using %e or %k in custom date format result in Thunar displaying current time in place of file modified time

[halogen2]

Xubuntu 20.04 live CD

Steps to reproduce:

1) Edit > Preferences > Date > Format, pick the "yyyy-mm-dd hh:mm:ss" option from the drop-down

2) Right-click any file (e.g. /usr/lib/chroot-setup.sh) > Properties. Note the modified and accessed times. Close the Properties dialog.

3) Back to Edit > Preferences, pick Custom date format. Set to:

%e %b %Y, %k:%M:%S

4) right-click the same file again > Properties

Expected results:

Same dates/times should be displayed at (2) and (4), just in different format.

Actual results:

At (4), the current date/time is displayed for Modified and Accessed.

Using stat in Terminal shows the times displayed with the preset option are the correct ones.

If I A) replace %e with %d, AND B) replace %k with %H, so the custom format becomes:

%d %b %Y, %H:%M:%S

Thunar does show correct dates/times with that custom format. Replacing only %e (keeping %k) results in Thunar showing correct date with completely wrong time.

Sorry for the late reply, I thought I had already replied to comment 2.

Indeed the upstream patch linked in comment 2 fixes this issue. Thanks @lastonestanding !

Can this please be SRU'd to focal?
