# Match the age of a file, for use as a glob qualifer. Can
# take one or two arguments, which can be supplied by one of two
# ways (always the same for both arguments):
#
# print *(e:age 2006/10/04 2006/10/09:)
#
# Match all files modified between the start of those dates.
#
# print *(e:age 2006/10/04)
#
# Match all files modified on that date. If the second argument is
# omitted it is taken to be exactly 24 hours after the first argument
# (even if the first argument contains a time).
#
# print *(e:age 2006/10/04:10:15 2006/10/04:10:45)
#
# Supply times. All the time and formats handled by calendar_scandate
# are allowed, but whitespace must be quoted to ensure age receives
# the correct arguments.
#
# AGEREF1=2006/10/04:10:15
# AGEREF2=2006/10/04:10:45
# print *(+age)
#
# The same example using the other form of argument passing. The
# dates stay in effect until unset, but will be overridden if
# any argument is passed in the first format.
