 * 		| Capability | Description |
 * 		|:------------|:-------------|
 * 		| `SET_TIME` | If the device can set the system time. |
 * 		| `SET_TIMEZONE` | If the device can set the system timezone. |
 * 		| `GET_TIMEZONE` | If the device can get the system timezone. |
 * 		| `NTP_TIME` | If the device can set the NTP server and system timezone. |
 *
 * 		If you want to check if the device supports those capabilities, use [`sos.management.supports()`](https://developers.signageos.io/sdk/sos_management/#supports).
