RE: expectation vs requirements for locale facets

[Mark Brown]

Hi Travis,

In my experience, the time_get facet isn't always able to reliably parse 
international times and cannot parse every time string produced by the time_put 
facet. I don't remember ever having problems with spaces though. On Linux at 
least, stdcxx has no problems skipping leading space in time strings. Which 
locale and what operating system does it not do so for you?
