i working on project using git repository , having issues. building app angular , have several .js , .css files. using grunt concatenate , minify these files because don't want include .css , .js files in main html file. doing have import 2 files, css , js file both concatenated. the easy solution use .gitignore on these files avoid constant merges in repository, thought too. building app angular, giving option build apps in phonegap , practically make native apps. problem ignoring concatenated .js , .css files build process needs these files build process. i think can solve problem having these files never pulled , overwritten on pushing. or have version of file on repository overwrite local version, , upon pushing running grunt again (we using grunt watch) , having local version overwrite version on repository. how guys solve such problem? may have read, have probable solutions, yet figure out how solve them. interested in solutions. i solve with: git update-

when marshall time.now() json object gives result "2009-11-10t23:00:00z" printing time.now gives 2009-11-10 23:00:00 +0000 utc . why different. t , z . how can convert swift nsdate object according this table? the meaning of values irrelevant, they're part of format (iso8601). there couple approaches this. 1 define custom marshaljson() method time or struct , use format date, other represent string in struct in first place when default implementation executes result you're looking for. the method you'll need use is; time.format(format string) golang docs show example using it; package main import ( "fmt" "time" ) func main() { // layout shows example how reference time should represented. const layout = "jan 2, 2006 @ 3:04pm (mst)" t := time.date(2009, time.november, 10, 15, 0, 0, 0, time.local) fmt.println(t.format(layout)) fmt.println(t.utc().format(layout)) } the medium date f
