This library converts default Go time format to strftime format.
layout := "Mon, 02 Jan 2006 15:04:05 -0700"
str2ftimeLayout, err := Go2Strftime(layout) // gives "%a, %d %b %Y %h:%M:%S %z"As it seems the conversion cannot be correctly done as the features supported by both formats are not equal. For example strftime cannot represent nanoseconds, but go cannot represent week numbers.
The package just replaces supported segments with strftime and does no any error checking otherwise.
