Solution

Quite simply, timestampClient does not exist (or is inaccessible) at each point where you see the underlined variable with that message.

If it needs instantiating then set whatever like:

TimestampClient timestampClient = new TimestampClient()

For this to work you need to ensure that you declare timestampClient somewhere accessible by your DisplayMessage method
