CharType Some C++ API could use a bit more calling convention consistency (1) - it looks like std::put_time() is meant only for streams, because it is meant for localization - so it can take advantage of the locale setting imbued into the stream, so while it is easy to use - it is not actually meant for general consumption outside the context of localized streams. converts a tm object to custom wide string textual representation. Great answer, but I would advise to not escape the type-system until the last minute. Could entrained air be used to increase rocket efficiency, like a bypass fan? first _Pt If _Mod equals zero, the effective format is "%F", where F is replaced by _Fmt. const TimePut& tp = std::use_facet(out.getloc()); All ordinary characters, including the terminating null character, are copied to the output string without modification. Here's one example using some C++11 features. When you instantiate. str Object of a class derived from ios_base (generally an output stream object). By clicking Post Your Answer, you agree to our terms of service and acknowledge that you have read and understand our privacy policy and code of conduct. If a std::time_put specialization is not guaranteed to be provided by the standard library (see below), the behaviors of its put() and do_put() are not guaranteed as specified. This is because mktime() depends on this value, but std::get_time() (and strptime()) does not set it. @BigDaveDev I took your advice and it became much nicer indeed. What if the numbers and words I wrote on my check don't match? Find centralized, trusted content and collaborate around the technologies you use most. strftime does not allow you to check how much space you'd need, except iteratively (see (1) again). Each such char element is assumed to map to an equivalent element of type CharType by a simple, one-to-one mapping. All ordinary characters, including the terminating null character, are copied to the output string without modification. Not the answer you're looking for? Connect and share knowledge within a single location that is structured and easy to search. However, this gives me time in HH::MM::SS.

When you use a stringstream to capture the localtime()'s output, you can store the string stored in stringstream by using .str(). Each conversion specification begins with % character, optionally followed by E or O modifier (ignored if unsupported by the locale), followed by the character that determines the behavior of the specifier. I'm trying to save the value returned into a variable such that I can do something like.

C++ Localizations library std::time_put Defined in header <locale> template< class CharT, class OutputIt = std::ostreambuf_iterator< CharT > > class time_put; Class template std::time_put encapsulates date and time formatting rules. The format string consists of zero or more conversion specifiers and ordinary characters (except %). For a percent followed by a character C in the interval [ first, last), the function instead evaluates next = do_put( next, _Iosbase, _Fill, _Pt, C, 0) and skips past C. If, however, C is a qualifier character from the set EOQ#, followed by a character C2 in the interval [ first, last), the function instead evaluates next = do_put( next, _Iosbase, _Fill, _Pt, C2, C) and skips past C2.
