3126	boost::format in debug build is no longer able to format time_duration with hours >= 100, as of svn rev 49874	mbd@…	Samuel Krempp	"https://svn.boost.org/trac/boost/changeset/49874 breaks boost::format's ability to format a time_duration if it has more than 99 hours. 

It is unclear from the docs whether this is intended behaviour or not. I believe it is because boost::format uses the default time_facet format of ""%H:%M:%S%F"". Had it been using ""%O:%M:%S%F"", I think there would have been no breakage(?)

The attached minimal program illustrates the problem."	Bugs	closed	Boost 1.40.0	date_time	Boost 1.38.0	Problem	duplicate	format time_duration	Samuel.Krempp@…
