notmuch appears to match specific date/times:

        date:<since>..<until> or date:<date>

DATE AND TIME SEARCH
        notmuch understands a variety of standard and
        natural ways of expressing dates and times, both in
        absolute terms ("2012-10-24") and in relative terms
        ("yesterday"). Any number of relative terms can be
        combined ("1 hour 25 minutes") and an absolute date/time
        can be combined with relative terms to further adjust it.

    The range expression
        [...]
        If specifying a time range using timestamps in
        conjunction with the date prefix, each timestamp must be
        preceded by @ (ASCII hex 40). As above, each timestamp
        is a number representing the number of seconds since
        1970-01-01 00:00:00 UTC. For example:
           date:@<initial-timestamp>..@<final-timestamp>
        [...]

    Single expression
        date:<expr> works as a shorthand for date:<expr>..<expr>.
        For example, date:monday matches from the beginning of
        Monday until the end of Monday.
