int8_t timezone_get_hours ( void  )

get the current timezone offset (hours)

Return values
timezoneoffset (hours)

References tz_hours.

Referenced by display_date_time_application(), set_date_application(), and set_time_application().

int8_t timezone_get_minutes ( void  )

get the current timezone offset (minutes)

Return values
timezoneoffset (minutes)

References tz_minutes.

Referenced by display_date_time_application(), set_date_application(), and set_time_application().

void timezone_init ( void  )

get and set timezone stored in EEPROM

This function will check if a timezone has been stored in EEPROM. If this is the case it will be set, and used by the date&time application. If it is not set, the "select timezone" application will be started to set it

References gfx_mono_menu::current_selection, nvm_eeprom_read_byte(), temp, timezone_select_application(), tz_hours, TZ_HOURS_EEPROM_ADDR, tz_index_to_minutes(), tz_minutes, and TZ_MINUTES_EEPROM_ADDR.

Referenced by main().

void timezone_select_application ( void  )

Select timezone application.

This application will show a menu with available timezone offset and set the selected timezone to be used by the date&time application. If the timezone setting differs from the already stored setting in EEPROM, the EEPROM value will be updated with the new selection.

int8_t tz_index_to_minutes ( uint8_t  tz_minutes_index)

Convert from tz_minute_menu index to actual minutes.

Parameters
tz_minutes_indexindex in tz_minutes menu
Return values
actualnumber of minutes timezone offset
