## show pcap timestamp

Emits the timestamping mode currently in use for each capture port. The list of possible values is the same as the range of valid arguments to [`config pcap timestamp mode`](/v1/docs/config-pcap#config-pcap-timestamp-mode).

```fmadiocli
show pcap timestamp
```

Example output:

```plaintext
[Thu Jan  1 00:00:00 1970] > show pcap timestamp
[Thu Jan  1 00:00:00 1970] CmdLine [show pcap timestamp]
[Thu Jan  1 00:00:00 1970] Cmd [show pcap timestamp ]
[Thu Jan  1 00:00:00 1970] Capture Timestamp Setting:
[Thu Jan  1 00:00:00 1970]   cap0: nic
[Thu Jan  1 00:00:00 1970]   cap1: nic
```
