How to convert Datetime to Unix timestamp in Io

🎈 🎈 🎈


    # Convert Date to Unix timestamp
    date := Date clone setYear(2014) setMonth(4) setDay(25) setHour(0) setMinute(25) setSecond(33)
    unixTimestamp := date secondsSince(Date fromString("1970-01-01"))
    
    writeln("Unix Timestamp: ", unixTimestamp)

Output:

Unix Timestamp: 1398385533

Example only. There may be multiple ways to perform this operation.

Code Explanation

In this example of date to Unix timestamp conversion using Io, a Date object is created for '2014-04-25 00:25:33' using the setYear, setMonth, setDay, and other methods.
The secondsSince method calculates the number of seconds between the given Date object and January 1, 1970 (Unix epoch), which returns the Unix timestamp. The result is '1398385533', which is printed.

`Date now()`	Returns the current date and time as a `Date` object.	`Date now()` returns 2024-08-28 12:34:56
`Date fromSeconds()`	Creates a `Date` object from a Unix timestamp (seconds since 1970).	`Date fromSeconds(1589530245)` returns 2020-05-15 08:10:45
`secondsSince()`	Returns the number of seconds since a given `Date` object.	`date secondsSince(Date fromString("1970-01-01"))` returns 1589530245
`Date setYear()`	Sets the year for the `Date` object.	`date setYear(2020)` sets the year to 2020.
`Date setMonth()`	Sets the month for the `Date` object (1 for January).	`date setMonth(5)` sets the month to May.
`Date setDay()`	Sets the day of the month for the `Date` object.	`date setDay(15)` sets the day to the 15th.
`Date setHour()`	Sets the hour for the `Date` object.	`date setHour(8)` sets the hour to 8 AM.
`Date setMinute()`	Sets the minutes for the `Date` object.	`date setMinute(30)` sets the minutes to 30.
`Date setSecond()`	Sets the seconds for the `Date` object.	`date setSecond(45)` sets the seconds to 45.
`Date asString()`	Returns the `Date` object as a string.	`date asString()` returns a formatted date string, such as 2020-05-15 08:10:45.
