This is the giant patch that makes various place use time_t for
timestamps instead of plain strings.
This allows us to do regular time operations on the provided
timestamps.

In the future we may also do some more processing on these timestamps
such as outputting 'human readable formats' like '5 seconds ago' etc.
A PoC has already been done by gjn.

Review and comments highly appreciated.

Nico

Nico Sonack (13):
  Add infrastructure for converting date values to use time_t instead of
    strings
  issues: Convert created_at to use a time_t
  pulls: convert created_at field to using a time_t
  table: teach table printer about timestamps
  json_util: parse a null time stamp as unset
  pipelines: convert timestamps to use time_t
  releases: convert timestamps to use time_t
  milestones: convert dates to use time_t
  forks: convert to using time_t for timestamps
  repos: convert to using time_t for timestamps
  sshkeys: convert to using time_t for timestamps
  attachments: convert to using time_t for timestamps
  comments: convert to using a time_t for timestamps
