Time Synchronization

warp1

ntp/state

The state of network time synchronization.

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

Name	Description
synced bool	Indicates whether the device was able to synchronize its time via NTP.
time int	A Unix timestamp in minutes indicating the device's current time, or 0 if no time synchronization exists

ntp/config

The configuration of network time synchronization.

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

Read

curl http://$HOST/ntp/config

{
  "enable": true,
  "use_dhcp": true,
  "timezone": "Europe/Berlin",
