gf712its just for time parsing10:11
gf712the standard doesnt handle timezone right now10:12
gf712basically its an extension of chrono10:12
wikingyeye just reading the slides10:12
gf712I need for date parsing10:12
gf712because get_time sucks apparently...10:13
wikinghehehe10:13
gf712I was away last week and tests failed because I was in a different timezone....10:13
wiking:>10:13
wikingcrazy stuff :)10:14

gf712wiking: would it be worth having a custom container in shogun to handle variants?14:00
wikingnoup14:00
wiking:D14:00
gf712i.e. SGMatrix<variant<float, date>> ?14:00
wikingeh14:00
wikingwhy would we want that? :)14:00
gf712because right now I just get the unix timestamp14:01
gf712from the date14:01
wikingand SGMat anyways is only good if you need something typemapped between interfaces14:01
wikingand?14:01
wikingi'm not so sure if i follow14:01
gf712and how would you handle a training set with numeric and string?14:01
wikingah14:01
wikingforgetaboutit14:01
wiking:)14:01
gf712well for date it might be not worth it14:01
wikingcombinedfeatures14:01
gf712you might want something else14:02
wikingif u wanna be able to represent various types14:02
wikingit's only combinedfeatures atm14:02
gf712ah14:03
gf712yea, I think this is what I need14:03
gf712wiking: btw, so date.h is working, but it needs to be compiled to parse timezone abbreviations14:04
gf712worth it?14:04
gf712otherwise it can only handle offsets14:04
wikingi mean it'll be compiled with the lib no?14:04
gf712no14:04
gf712it needs to be build14:05
gf712separately14:05
wikingwhy?14:05
gf712I guess it check some os stuff14:05
gf712and gets timezone info14:05
gf712but it's just for the timezone abbreviations14:05
wikingdont get it14:05
gf712all the rest works fie14:05
wikingwhy does it have to be compiled separately14:06
wiking:)14:06
wikingbut if that's needed14:06
wikingthen we should include it differently14:06
gf712I mean I can have a look at the lib to see why14:06
gf712ah14:06
gf712it does a locate timezone14:06
gf712and I'm guessing locale is determined at compile time14:06
wikingbut14:07
wikingthen this is useless14:07
gf712but then again this is going into stl14:07
wikingi mean its not portable?14:07
gf712well, there's a utility to determine your own timezone14:07
gf712I don't use it14:08
wikingque?14:08
wikingcan you point me to line of coe14:08
wiking*code14:08
gf712date::locate_zone(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)14:08
gf712I get this linker error without the compiled lib14:08
wikingthat's fine14:08
wikingi'm not understanding14:08
wikingwhy cannot this be compiled14:08
wikingwithin shogun14:08
wikingbut i'll look it at14:08
wikingforgetaboutit14:08
gf712https://github.com/HowardHinnant/date/blob/master/src/tz.cpp this is all config stuff that has to be in a cpp file14:12
wikingbut this object could b eadded within the lib i guess14:13
wikinglib = libshogun14:13
wikinguff14:14
wikingTARGET_OS_IPHONE14:14
wikingok forget about it14:14
wikingthis is bs14:14
wiking:)14:14
wikingcoz this makes life harder with precompiled binary packages14:14
gf712aight, I'll just have the header files14:16
gf712and throw an error if the file requires timezone abbreviations14:16
