Member Function Documentation

execute()

virtual void uniot::Date::execute ( short _ )

inlineoverridevirtual

Periodic execution callback.

Called periodically to store the current time to persistent storage.

Parameters

_	Unused parameter required by IExecutor interface

Implements uniot::IExecutor.

forceSync()

void uniot::Date::forceSync ( )

inline

Forces immediate NTP time synchronization.

Reconfigures the NTP client and initiates an immediate time sync request regardless of the regular sync schedule.

getFormattedTime()

static String uniot::Date::getFormattedTime ( )

inlinestatic

Gets the current time in human-readable format.

Return values

String

Time in "YYYY-MM-DD HH:MM:SS" format

now()

static time_t uniot::Date::now ( )

inlinestatic

Returns the current Unix timestamp.

Return values

time_t

Current time as Unix timestamp (seconds since epoch)

restore()

bool uniot::Date::restore ( )

inlineoverridevirtual

Restores time from persistent storage.

Loads the last saved epoch time from CBOR storage and sets the system time accordingly.

Return values

true	Restore operation was successful
false	Restore operation failed

Reimplemented from uniot::CBORStorage.

store()

bool uniot::Date::store ( )

inlineoverridevirtual

Stores the current time to persistent storage.

Saves the current epoch time to CBOR storage to preserve time information between device reboots.

Return values

true	Storage operation was successful
false	Storage operation failed

Reimplemented from uniot::CBORStorage.
