How to convert Unix timestamp to Datetime in Nim

🎈 🎈 🎈


    import times

    # Convert Unix timestamp to Date
    let unixTimestamp: int64 = 1721829396
    let date = fromUnix(unixTimestamp)
    
    echo "Converted Date: ", date.format("yyyy-MM-dd HH:mm:ss")

Output:

Converted Date: 2024-07-24 13:56:36

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

Code Explanation

In order to convert a Unix timestamp to a date in Nim the Unix timestamp 1721829396 is passed to the fromUnix function, which converts the Unix timestamp into a Time object.
The format function is then used to format the Time object into a readable string, which is then printed as 2024-07-24 13:56:36.

Other useful Nim date functions

Function	Description	Example
`now()`	Returns the current date and time as a `Time` object.	`now()` returns 2024-08-28 12:34:56
`fromUnix()`	Converts a Unix timestamp (in seconds) to a `Time` object.	`fromUnix(1589530245)` returns 2020-05-15 08:10:45
`toUnix()`	Converts a `Time` object to a Unix timestamp (in seconds).	`toUnix(initDateTime(2020, 5, 15, 8, 30, 45))` returns 1589530245
`initDateTime()`	Initializes a `Time` object for the given year, month, day, hour, minute, and second.	`initDateTime(2020, 5, 15, 8, 30, 45)` creates 2020-05-15 08:10:45
`format()`	Formats a `Time` object as a string using a specified format.	`time.format("yyyy-MM-dd HH:mm:ss")` returns 2020-05-15 08:10:45
`parse()`	Parses a date string and returns a `Time` object.	`parse("2020-05-15 08:10:45", "yyyy-MM-dd HH:mm:ss")` returns a Time object.
`addSeconds()`	Adds a number of seconds to a `Time` object.	`addSeconds(now(), 3600)` adds 1 hour to the current time.
`toLocal()`	Converts a UTC `Time` object to local time.	`now().toLocal()` converts the current UTC time to local time.
`dayOfWeek()`	Returns the day of the week (0=Sunday, 6=Saturday) for a `Time` object.	`dayOfWeek(now())` returns the current day of the week.
