Graphite at(1) support

[ghost]

What is the state of at(1) support?

The render API states ABSOLUTE_TIME is in the format HH:MM_YYMMDD, YYYYMMDD, MM/DD/YY, or any other at(1)-compatible time format., and yet the examples just below that don't follow at behaviour at all.

Example:
&from=january+1 (shows data since the beginning of the current year)

$ echo 'ls' | at january 1
job 1 at Sun Jan 1 12:34:00 2017

Not only does it use the current time of day, it uses january 1 of next year, not the current year.

Or possibly my favourite; this works in graphite: &from=janthisisntreallyamonth+1
