Ethereum Date and Time tools

Contract which implements utilities for working with datetime values in ethereum.

Contract Deployments:

To verify, you need to compare the code on the blockchain with the runtime code which can be gotten from

solc contracts/DateTime.sol --optimize --bin-runtime
.

Also you can find it already verified at https://etherscan.io/address/0x1a6184cd4c5bea62b0116de7962ee7315b7bcbce#code

DateTime struct

Internally, the following struct is used to represent date-time object.

struct DateTime {
        uint16 year;
        uint8 month;
        uint8 day;
        uint8 hour;
        uint8 minute;
        uint8 second;
        uint8 weekday;
}

API

  • isLeapYear(uint16 year) constant returns (bool)

Given an integer year value, returns whether it is a leap year.

  • parseTimestamp(uint timestamp) internal returns (DateTime dt)

Given a unix timestamp, returns the

DateTime
representation of it.
  • getYear(uint timestamp) constant returns (uint16)

Given a unix timestamp, returns the

DateTime.year
value for the timestamp.
  • getMonth(uint timestamp) constant returns (uint16)

Given a unix timestamp, returns the

DateTime.month
value for the timestamp.
  • getDay(uint timestamp) constant returns (uint16)

Given a unix timestamp, returns the

DateTime.day
value for the timestamp.
  • getHour(uint timestamp) constant returns (uint16)

Given a unix timestamp, returns the

DateTime.hour
value for the timestamp.
  • getMinute(uint timestamp) constant returns (uint16)

Given a unix timestamp, returns the

DateTime.minute
value for the timestamp.
  • getSecond(uint timestamp) constant returns (uint16)

Given a unix timestamp, returns the

DateTime.second
value for the timestamp.
  • getWeekday(uint timestamp) constant returns (uint8)

Given a unix timestamp, returns the

DateTime.weekday
value for the timestamp.
  • toTimestamp(uint16 year, uint8 month, uint8 day, uint8 hour, uint8 minute, uint8 second) constant returns (uint timestamp)
  • toTimestamp(uint16 year, uint8 month, uint8 day, uint8 hour, uint8 minute) constant returns (uint timestamp)
  • toTimestamp(uint16 year, uint8 month, uint8 day, uint8 hour) constant returns (uint timestamp)
  • toTimestamp(uint16 year, uint8 month, uint8 day) constant returns (uint timestamp)

Returns the unix timestamp representation for the given date and time values.
