#
# print *(e:after 2014/08/01:)
# print *(e-after today:12:00-)
#
# If named before:
# Match files modified before a given time.
#
# If named after:
# Match files modified after a given time. Use as glob qualifier.
# N.B.: "after" actually includes the given time as it is to second
# precision (it would be inconvenient to exclude the first second of a date).
# It should therefore more logically be called "from", but that's a less
# obvious name.
#
# File to test is in $REPLY.
#
# Similar to age, but only takes at most one data, which is
# compared directly with the current time.
