removed FLBTime because uint64 interface cannot be converted to int64

[guineveresaenger]

The code as written cannot be converted into FLBTime. Unix time is consistently displayed in the Time field across plugins; perhaps this is an issue that can be addressed in fluent-bit code base?

Disclaimer: I'm a novice at golang and would be more than happy to learn about a different way to re-type the time and display it as human readable.

@guineveresaenger I faced the same issue, and i added the following code to prevent crashes:

var timeStamp string
switch t := ts.(type) {
case output.FLBTime:
	timeStamp = ts.(output.FLBTime).String()
case uint64:
	timeStamp = time.Unix(int64(t), 0).Format(timeFormat)
default:
	fmt.Print("given time is not in a known format, defaulting to now.\n")
	timeStamp = time.Now().Format(timeFormat)
}
