```go ```go
// Normal parse // Normal parse. If no recognized Timezone/Offset info
// exists in the datestring, it uses UTC.
t, err := dateparse.ParseAny("3/1/2014") t, err := dateparse.ParseAny("3/1/2014")
// Parse with Location // Parse with Location. If no recognized Timezone/Offset info
// exists in the datestring, it uses given location.
// IF there IS timezone/offset info it uses the given location
// info for any zone interpretation. That is, MST means one thing
// when using America/Denver and something else in other locations.
denverLoc, _ := time.LoadLocation("America/Denver") denverLoc, _ := time.LoadLocation("America/Denver")
t, err := dateparse.ParseIn("3/1/2014", denverLoc) t, err := dateparse.ParseIn("3/1/2014", denverLoc)
// Set Location to time.Local. Same as ParseIn Location but
// Lazily uses a global variable for Location Info.
denverLoc, _ := time.LoadLocation("America/Denver")
// use time.Local global variable to store location
time.Local = denverLoc
t, err := dateparse.ParseLocal("3/1/2014")
