Detailed Description

Retrieve and maintain UnixTime clock.

This module requires a UnixTime service running in the local network.

See also: https://github.com/yoursunny/ndn6-tools/blob/main/unix-time-service.md

This module periodically retrieves the current Unix timestamp from the service, and then updates the system clock via ndnph::port::UnixTime::set function. The current Unix time is then available via ndnph::port::UnixTime::now function as well as gettimeofday() and other system functions.

This module cannot be used together with other time synchronization mechanisms such as lwip SNTP client.

Member Function Documentation

◆ begin()

void esp8266ndn::UnixTime::begin ( int interval = 60000 )

Enable UnixTime requests.

Parameters

interval how often to refresh time (millis), minimum 5000ms.

◆ loop()

void esp8266ndn::UnixTime::loop ( )

finalprivatevirtual

Override to be invoked periodically.

Reimplemented from ndnph::PacketHandler.

◆ processData()

bool esp8266ndn::UnixTime::processData ( ndnph::Data )

finalprivatevirtual

Override to receive Data packets.

Return values

true	packet has been accepted by this handler.
false	packet is not accepted, and should go to the next handler.

Reimplemented from ndnph::PacketHandler.
