Multiple output files doesn't use the correct "SetFlags"

[sandebains]

I'm using the below configuration where multiple files are in use for writing logs. However with the SetFlags options in place, I noticed that only first file adhere to the settings. Rest of the files fall back to generic option where the "code line numbers" are being printed.

Code Snippet (Initializing files and logger):

lf2, err := os.OpenFile("log/server.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0660)
if err != nil {
	logger.Fatalf("Failed to open log file: %v", err)
}
defer lf2.Close()
lf3, err := os.OpenFile("log/auth.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0660)
if err != nil {
	logger.Fatalf("Failed to open log file: %v", err)
}
defer lf3.Close()
glogger = logger.Init("Websockets Logger", false, false, lf)
defer glogger.Close()

Ologger = logger.Init("General Logger", false, false, lf2)
defer Ologger.Close()

userlogger = logger.Init("Authentication Logger", false, false, lf3)
defer userlogger.Close()

logger.SetFlags(log.LstdFlags | log.LUTC)
