>Description:
GNATS should allow a date query relative to the current date. I understand I 
can query with an expression that includes an explicit date, but such queries 
make little sense when saved.

For example, I might wish to see every PR that arrived today. If I construct a 
query using today's date and save it, I can't use the same query tomorrow to 
show me the PRs that arrived that day. Instead, I have to construct a new query 
each day.

I'd like to be able to specify a date like "-5" -- meaning five days prior to 
today ("-0" could mean today).

Chad Walstrom points out that the use of descriptive time units similar to 
at(1) would probably be preferable:

The equivalent line in at(1) would be: "at now - COUNT TIME_UNITS" or "at now - 
5 days".  In addition to the "now" alias, there are "yesterday", "tomorrow", 
and "midnight", "noon", and even "teatime". Time units can be "minutes", 
"hours", "days", or "weeks". To translate that into query-pr syntax:

        $ query-pr --expr 'Arrival-Date="today"'

or
        $ query-pr --expr 'Arrival-Date<"now - 3 hours"
