#12699: posix_time\time_formatters removes trailing 0 fractional seconds
-----------------------------------------------+------------------------
 Reporter:  Jonathan Zuber <jonathan.zuber@…>  |      Owner:  az_sw_dude
     Type:  Feature Requests                   |     Status:  new
Milestone:  To Be Determined                   |  Component:  date_time
  Version:  Boost 1.63.0                       |   Severity:  Cosmetic
 Keywords:  Time, Fractional Seconds,          |
-----------------------------------------------+------------------------
 When calling boost::posix_time::to_iso_extended_string(), the returned
 format will differ depending on the value of the fractional seconds.  This
 cannot be configured.  In time_formatters.hpp, function
 'to_simple_string_type' checks if the value of the fractional seconds is 0
 (zero).  If it is, it will not print the corresponding fractional seconds
 digits.

 I consider this a bug because if one is to display multiple ptimes in this
 format they could have differing widths which would not be visually
 appealing.

 I propose that this is changed to be either:

 1) User controlled.  The user can set whether or not to print the
 characters.

 OR

 2) It should always print the fractional seconds digits.

 I believe that option 1) is the correct solution, though at the very least
 I believe option 2) to be more correct than the current implementation.
