How to convert Datetime to Unix timestamp in Racket

🎈 🎈 🎈


    #lang racket

    ; Convert Date to Unix timestamp
    (define my-date (date 2024 2 28 8 45 22 0 0 0))
    (define unix-timestamp (date->seconds my-date))
    
    ; Display the Unix timestamp
    (printf "Unix Timestamp: ~a\n" unix-timestamp)

Output:

Unix Timestamp: 1709109922

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

Code Explanation

In this Racket example, the date function is used to create a date structure for the date '2024-02-28 08:45:22'. This date structure is then converted to a Unix timestamp using date->seconds.
The Unix timestamp is then printed using the printf function.

Function	Description	Example
`seconds->date`	Converts a Unix timestamp to a `date` structure.	`(seconds->date 1514764800)` returns 2018-01-01 00:00:00
`date->seconds`	Converts a `date` structure to a Unix timestamp.	`(date->seconds (date 2018 7 15 12 30 45 0 0 0))` returns 1531656645
`current-seconds`	Returns the current Unix timestamp.	`(current-seconds)` returns the current Unix timestamp.
`date`	Creates a `date` structure with the given year, month, day, hour, minute, second, etc.	`(date 2018 7 15 12 30 45 0 0 0)` creates the date 2018-07-15 12:30:45
`date-year`	Extracts the year from a `date` structure.	`(date-year (seconds->date 1514764800))` returns 2018
`date-month`	Extracts the month from a `date` structure.	`(date-month (seconds->date 1514764800))` returns 1 (January)
`date-day`	Extracts the day of the month from a `date` structure.	`(date-day (seconds->date 1514764800))` returns 1
`date-hour`	Extracts the hour from a `date` structure.	`(date-hour (seconds->date 1514764800))` returns 0
`date-minute`	Extracts the minute from a `date` structure.	`(date-minute (seconds->date 1514764800))` returns 0
`date-second`	Extracts the second from a `date` structure.	`(date-second (seconds->date 1514764800))` returns 0
