strftime For Go
Q: Why, we already have time.Format?
A: Yes, but it becomes tricky to use if if you have string with things other than time in them. (like /path/to/%Y/%m/%d/report)
go get bitbucket.org/tebeka/strtime
str, err := strftime.Format("%Y/%m/%d", time.Now())
The following directive are not supported
