Readme file for Arduino Time Library

Time is a library that provides timekeeping functionality for Arduino.

The functions available in the library include:

minute(); // the minute now (0-59)
second(); // the second now (0-59)
minute(); // the minute now (0-59)
second(); // the second now (0-59)

month(); // the month now (1-12)
year(); // the full four digit year: (2009, 2010 etc)
year(); // the full four digit year: (2009, 2010 etc)

there are also functions to return the hour in 12 hour format
hourFormat12(); // the hour now in 12 hour format
isAM(); // returns true if time now is AM
isAM(); // returns true if time now is AM
isPM(); // returns true if time now is PM

now(); // returns the current time as seconds since Jan 1 1970
now(); // returns the current time as seconds since Jan 1 1970

The time and date functions can take an optional parameter for the time. This prevents
errors if the time rolls over between elements. For example, if a new minute begins
between getting the minute and second, the values will be inconsistent. Using the
following functions eliminates this probglem
time_t t = now(); // store the current time in time variable t

- TimeRTC uses a DS1307 real time clock to provide time synchronization.
A basic RTC library named DS1307RTC is included in the download.
To run this sketch the DS1307RTC library must be installed.

- TimeRTCLog demonstrates how to calculate the difference between times.
It is a vary simple logger application that monitors events on digtial pins
and prints (to the serial port) the time of an event and the time period since the previous event.

- TimeNTP uses the Arduino Ethernet shield to access time using the internet NTP time service.
The NTP protocol uses UDP and the UdpBytewise library is required, see:

although the Time library is based on the DateTime codebase, the API has changed.
Changes in the Time library API:
- time elements are functions returning int (they are variables in DateTime)
- Years start from 1970
- Years start from 1970
- days of the week and months start from 1 (they start from 0 in DateTime)
- DateStrings do not require a seperate library
- time elements can be accessed non-atomically (in DateTime they are always atomic)
- function added to automatically sync time with extrnal source
- localTime and maketime parameters changed, localTime renamed to breakTime

Technical notes:

Internal system time is based on the standard Unix time_t.
The value is the number of seconds since Jan 1 1970.
System time begins at zero when the sketch starts.

The internal time can be automatically synchronized at regular intervals to an external time source.
This is enabled by calling the setSyncProvider(provider) function - the provider argument is
the address of a function that returns the current time as a time_t.
See the sketches in the examples directory for usage.

The default interval for re-syncing the time is 5 minutes but can be changed by calling the
The default interval for re-syncing the time is 5 minutes but can be changed by calling the
setSyncInterval( interval) method to set the number of seconds between re-sync attempts.

The Time library defines a structure for holding time elements that is a compact version of the C tm structure.
All the members of the Arduino tm structure are bytes and the year is offset from 1970.
Convenience macros provide conversion to and from the Arduino format.

Low level functions to convert between system time and individual time elements are provided:
Low level functions to convert between system time and individual time elements are provided:
breakTime( time, &tm); // break time_t into elements stored in tm struct
makeTime( &tm); // return time_t from elements stored in tm struct
makeTime( &tm); // return time_t from elements stored in tm struct

The DS1307RTC library included in the download provides an example of how a time provider
can use the low level functions to interface with the Time library.
