ace_time::TimeZoneData Struct Reference

Data structure that captures the internal state of a TimeZone object with enough information so that it can be serialized using TimeZone::toTimeZoneData() then reconstructed using ZoneManager::createForTimeZoneData(). More...

#include <TimeZoneData.h>

Public Member Functions
	TimeZoneData (uint32_t zid)
	Constructor for kTypeZoneId needed because C+11 does not have member initialization, and cannot initialize the 'zoneId' component of the union.
	TimeZoneData (int16_t stdMinutes, int16_t dstMinutes)
	Constructor for kTypeManual.
	TimeZoneData ()
	Default constructor gives kTypeError sentinel.

Public Attributes
uint8_t	type
union {
struct {
int16_t   stdOffsetMinutes
int16_t   dstOffsetMinutes
}
	Used for kTypeManual. More...
uint32_t   zoneId
	Both TimeZone::kTypeBasic and TimeZone::kTypeExtended are mapped to a TimeZoneData::kTypeZoneId.

Static Public Attributes
static const uint8_t	kTypeError = 0
static const uint8_t	kTypeManual = 1
static const uint8_t	kTypeZoneId = 2

Detailed Description

Data structure that captures the internal state of a TimeZone object with enough information so that it can be serialized using TimeZone::toTimeZoneData() then reconstructed using ZoneManager::createForTimeZoneData().

This data structure is meant to a simple and somewhat opaque serialization object. You should not rely on this struct to remain stable, nor reach into its internal fields. No versioning is provided for simplicity. If the internal format changes in the future, the previous version will likely be incompatible with the new version of the library. It is recommended to use a CRC check to detect version incompatibility if this data structure is saved (e.g. EEPROM) and retrieved later .

For convenience, an array of TimeZoneData can be initializeed using the usual initializer syntax. In other words, the following is allowed:

TimeZoneData zones[3] = {
  {0, 0},
  {zonedb::kZoneIdAmerica_Los_Angeles},
  {}
};
