How to convert Datetime to Unix timestamp in Gleam

🎈 🎈 🎈


    import gleam/time

    pub fn date_to_unix(date: time.Time) -> Int {
        let unix_timestamp = time.to_unix_time(date)
        unix_timestamp
    }

Output:

1052603445

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

Code Explanation

In this Gleam snippet, time.to_unix_time is used to convert a time.Time structure back into a Unix timestamp.
This function returns an integer that represents the number of seconds since the Unix epoch (January 1, 1970).
Gleam's time.Time structure holds the date-time components and can be converted back into this standard format. For the date value of '2003-05-10 21:50:45', a Unix timestamp of '1052603445' would be returned.

Function	Description	Example
`time.now()`	Returns the current time as a `time.Time` type.	`time.now()` returns Time{2024, 9, 5, 14, 55, 0}
`time.from_unix_time(seconds)`	Converts a Unix timestamp to a `time.Time` structure.	`time.from_unix_time(1609459200)` returns Time{2021, 1, 1, 0, 0, 0}
`time.to_unix_time(time)`	Converts a `time.Time` structure to a Unix timestamp.	`time.to_unix_time(date)` returns 1609459200
`time.add_seconds(time, seconds)`	Adds a number of seconds to a `time.Time` structure.	`time.add_seconds(now, 3600)` adds 1 hour to the current time.
`time.diff_seconds(a, b)`	Calculates the difference in seconds between two `time.Time` structures.	`time.diff_seconds(time1, time2)` returns the difference in seconds between two times.
