Detailed Description
This contains all time functionality.
Function Documentation
◆ gos_time_get_current_utc_as_iso8601()
gos_result_t gos_time_get_current_utc_as_iso8601 | ( | gos_iso8601_t * |
iso8601_struct,
|
bool |
add_timezone
|
||
) |
Returns the current time as a gos_iso8601_t struct.
This has similar functionality to gos_time_get_current_utc_ms() except the current time is returned as a gos_iso8601_t
- Parameters
-
[out] iso8601_struct
Buffer to hold the current time as a gos_iso8601_t [in] add_timezone
If true then include the timezone offset in the returned value, if false then return UTC time with 0 timezone offset
- Returns
- gos_result_t result of api call
◆ gos_time_get_current_utc_as_iso8601_str()
gos_result_t gos_time_get_current_utc_as_iso8601_str | ( | gos_iso8601_str_t * |
iso8601_str,
|
bool |
add_timezone
|
||
) |
Returns the current time as a gos_iso8601_str_t .
This has similar functionality to gos_time_get_current_utc_ms() except the current time is returned as a gos_iso8601_str_t
- Note
-
The returned
iso8601_str
is null-terminated and can be directly printed as a string
- Parameters
-
[out] iso8601_str
Buffer to hold the current time as a gos_iso8601_str_t [in] add_timezone
If true then include the timezone offset in the returned value, if false then return UTC time with 0 timezone offset
- Returns
- gos_result_t result of api call
◆ gos_time_get_current_utc_ms()
gos_result_t gos_time_get_current_utc_ms | ( | gos_utc_ms_t * |
utc_time_ms,
|
bool |
add_timezone
|
||
) |
Returns the current UTC time in milliseconds.
This returns the current time as the number of milliseconds since the Epoch. i.e. This returns UNIX time.
- Note
-
If the
time.zone
variable is set and
add_timezone
is true then the timezone will be included in the returned value.
The current time may be set with gos_time_set_current_utc_ms() . However, the recommended approach is to use Network Time Protocol (NTP) to retrieve the time from the network, see ntp.enabled . Additionally, see gos_ntp_update() for more details about obtaining the current UTC time via NTP.
This API will return GOS_NEVER_SET if the time was never set.
- Note
- The value returned by this API is maintained by Real-Time Clock (RTC) hardware. The time will persist through reboots and resets as long as the device is powered.
See time.rtc for more details.
- Parameters
-
[out] utc_time_ms
Buffer to hold the current time [in] add_timezone
If true then include the timezone offset in the returned value, if false then return UTC time with 0 timezone offset
- Returns
- gos_result_t result of api call
◆ gos_time_get_current_utc_seconds()
gos_result_t gos_time_get_current_utc_seconds | ( | gos_utc_seconds_t * |
utc_time_seconds_ptr,
|
bool |
add_timezone
|
||
) |
Returns the current time in seconds.
This has similar functionality to gos_time_get_current_utc_ms() except the current time is returned as a gos_utc_seconds_t
- Parameters
-
[out] utc_time_seconds_ptr
Buffer to hold the current time in seconds [in] add_timezone
