[pkg-boost-devel] Bug#473177: libboost-date-time-dev: time_formatters.hpp incorrectly formats fractional seconds using global locale

[LeJacq, Jean Pierre]

Package: libboost-date-time-dev
Version: 1.34.1-9
Severity: important
Tags: patch


The function boost::posix_time::to_iso_string_type() uses the
ostream::operator<<() function to write the time. This later function
will use the current global locale to format each of the elements of
the time. In particular, when the global locale is set to en_US, the
fractional will be formatted to be 123,456 when there are six digits,
which is incorrect.
 
The proposed solution is to temporarily imbue the ostream with the
classic locale to disable formatting. The attached patch only applies
this to the fractional seconds but it would be more robust to apply to
the other time components as well.

This defect has already been reported upstream
http://svn.boost.org/trac/boost/ticket/1726.

This defect is similar to Debian Bug#469771.
