We have to identify and extract the date from given samplese

Oct  4 07:44:45  cli[1290]: PAPI_Send: To: 7f000001:8372 Type:0x4 Timed out. 

Oct  4 08:16:01  webui[1278]: USER:admin@192.168.100.205 COMMAND:<wlan ssid-profile "MFI-SSID" > -- command executed successfully 

Oct  4 08:16:01  webui[1278]: USER:admin@192.168.100.205 COMMAND:<wlan ssid-profile "MFI-SSID" opmode opensystem > -- command executed successfully
