Solve the following python programming problem given the following code:
def PopulateData(token = None) : 
    'Populates some usage information into the data store.' 
    flows = ['ListDirectory', 'GetFile', 'Flow1', 'KillFlow', 'Interrogate'] 
    def SimulateUserActivity(username, client_id, timestamp, num = 10) : 
        for flow_name in flows [: num] : 
            event = flow.AuditEvent (user = username, action = 'RUN_FLOW', flow_name = flow_name, client = client_id, age = timestamp) 
            flow.Events.PublishEvent ('Audit', event, token = token) 
now = int (rdfvalue.RDFDatetime ().Now ()) 
    week_duration = ((((7 * 24) * 60) * 60) * 1000000.0) 
    SimulateUserActivity ('test', 'C.0000000000000001', now) 
    SimulateUserActivity ('test', 'C.0000000000000002', now) 
    SimulateUserActivity ('admin', 'C.0000000000000001', now) 
    SimulateUserActivity ('user', 'C.0000000000000003', now) 
    SimulateUserActivity ('test', 'C.0000000000000001', (now - week_duration)) 
    SimulateUserActivity ('admin', 'C.0000000000000001', (now - week_duration)) 
    SimulateUserActivity ('user', 'C.0000000000000001', (now - (2 * flows))) 
    SimulateUserActivity ('admin', 'C.0000000000000001', (now - (2 * week_duration))) 
    test_lib.MockWorker (token = token).Simulate () 

    
    

    Fix the buggy line: SimulateUserActivity ('user', 'C.0000000000000001', (now - (2 * flows)))
