time-to-seconds

Unopinionated time to seconds converter that lets you decide the format of your h:m:s; as long as you keep the number of colons between 0 and 2 it does not matter if you use "hh:mm:ss", "h:m:s" or "hhh:mmmm:ssss" format - you will always get the number of seconds back as an integer.

Usage

Pass time as a string, e.g.:

• "h:m:s"
• "m:s"
• ":s"
• "s"
• or any variation of "h:m:s", e.g. ":m:s"; as long as you keep the number of colons between 0 and 2, where h, m or s are any numbers, you will get seconds - as a number - in return.

Examples

var timeToSeconds = require("time-to-seconds");

timeToSeconds("2:2:2");
// => 7322

timeToSeconds("02:02:02");
// => 7322

timeToSeconds("2:02:02");
// => 7322

timeToSeconds("2:2:02");
// => 7322

timeToSeconds("2:");
// => 120

timeToSeconds("2:0");
// => 120

timeToSeconds("02:0");
// => 120

timeToSeconds("02:00");
// => 120

timeToSeconds(":2");
// => 2

timeToSeconds("2");
// => 2

timeToSeconds("0:2");
// => 2

timeToSeconds("0:02");
// => 2

timeToSeconds("00:02");
// => 2

timeToSeconds("");
// => 0

timeToSeconds("0");
// => 0

Empty Strings

The non-strict format will allow for the input of an empty string which will be treated the same as passing the number 0; the below inputs are equivalent and will return 0 seconds:

• timeToSeconds("")
• timeToSeconds("0")
• timeToSeconds(":0")
• timeToSeconds("::0")
• timeToSeconds(":")
• timeToSeconds("::")

Error Handling

timeToSeconds("Anything else than time string");
// TypeError: 'time-to-seconds: wrong argument type - something else than a number string in format "number", "number:number" or "number:number:number" was passed. See documentation for more information on argument formatting: https://www.npmjs.com/package/time-to-seconds.'

timeToSeconds("2:2:2:2");
// TypeError: 'time-to-seconds: too many colons - make sure the function argument is a number string in format "number", "number:number" or "number:number:number". See documentation for more information on argument formatting: https://www.npmjs.com/package/time-to-seconds.'

Decimal Numbers

If you pass decimals to the function, e.g.:

• timeToSeconds("0.2:00") or
• timeToSeconds("0.2:")

(in the above examples the inputs are the same) it will be interpreted as 0.2 of one minute, so 12 seconds (60 * 0.2 = 12 seconds).

Similarly, if you pass, e.g.:

• timeToSeconds("0.2:00:00") or
• timeToSeconds("0.2::")

(again, the inputs are the same) it will be interpreted as 0.2 of one hour, so 720 seconds (3600 * 0.2 = 720 seconds).

Together:

• timeToSeconds("0.2:0.2:00") or
• timeToSeconds("0.2:0.2:")

will return 732 seconds (0.2 of one hour is 720 seconds, 0.2 of one minute is 12 seconds; 720 + 12 = 732 seconds)

Note: passing decimals as seconds, e.g.: timeToSeconds("0:0:0.2"), will simply return 0.2 seconds.

Math

You could calculate the value to convert and because of the non-strict format, pass the calcualted value to the function, e.g.:

var num = Math.log10(100);
timeToSeconds(`${num.toString()}:`);
// => 120

timeToSeconds(`${Math.log10(100).toString()}:`);
// => 120
