When I run cf-agent, I see many errors like this:

2015-11-28T04:02:40+0100     info: /default/schedule_simple_generic/vars/'max_execution_delay'[0]: Error reading assumed integer value '${max_execution_delay_real}' => 'non-value', found remainder ''
2015-11-28T04:02:40+0100     info: /default/schedule_simple_generic/vars/'max_execution_delay'[0]: The variable might not yet be expandable - not necessarily an error

They come from the int variables in time_lib.cf. Replacing the ints with strings seems to work just fine (according to the simple_schedule test).
