You are using the wrong cdef in your warning definition!  So, of course you
get the end time of the graph...

options.push("VDEF:#{c}warning=#{c}limit,MINIMUM")

Define your warning on the limited CDEF.  Now, #{c}limit becomes unknown
when #{c}avg drops below 0.  Therefore, the minimum value of #{c}warning
must be 0 (if it reaches 0) and so the strftime for this point will be the
time it hits 0.
