[PATCH] tools: fix date parsing in patchwork polling

[David Marchand <david.marchand@redhat.com>]

Though it is not fully understood why (maybe some system upgrade..?),
parsing date is now failing on some long running Debian system.

Specify date format earlier in the command line.

Fixes: baaec1836189 ("tools: filter new patchwork IDs by date")
