halopsa-v0.2.7

Fixed

• --since now accepts the RFC3339 timestamps its own help documents. The
  parser folded its input to lowercase before trying any format, and because
  time.Parse matches layout characters literally, the uppercase T separator
  and Z designator no longer matched, so every timestamp was rejected as an
  unrecognized time. The fold is still applied to keywords and durations, which
  need it: time.ParseDuration rejects uppercase unit letters, so 24H and
  7D only work because of it. Affects standup, agent workload,
  sla scorecard, tickets age-out and tickets reopens, all of which
  document RFC3339 and all of which rejected it. Thanks to @geekbrownbear for
  the report and the fix (#219).
