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.
