Should timestamp be in seconds or milliseconds?

One doesn’t commonly need to concern themselves with this, however. Traditionally, Unix timestamps were defined in terms of whole seconds. However, many modern programing languages (such as JavaScript and others) give values in terms of milliseconds.

How do I read a Unix timestamp?

To find the unix current timestamp use the %s option in the date command. The %s option calculates unix timestamp by finding the number of seconds between the current date and unix epoch. You will get a different output if you run the above date command.

What is FFFF timestamp?

ffff are ten thousandths of a second. The “FF” custom format specifier represents the two most significant digits of the seconds fraction; that is, it represents the hundredths of a second in a date and time value. MySQL retrieves and displays DATETIME values in ‘ YYYY-MM-DD hh:mm:ss ‘ format. …

How do I convert a timestamp?

In this article, we will show you how to convert UNIX timestamp to date.

Convert Timestamp to Date.

1. In a blank cell next to your timestamp list and type this formula =R2/86400000+DATE(1970,1,1), press Enter key.
3. Now the cell is in a readable date.

What is current timestamp?

The CURRENT TIMESTAMP (or CURRENT_TIMESTAMP) special register specifies a timestamp that is based on a reading of the time-of-day clock when the SQL statement is executed at the application server.

How do I pass a timestamp in API?

Instead use a conditional GET request. This will also tell you that the timestamp to pass to the service will need to be in a format specified in Date and Time Specification section of RFC 2822. Every programming language will have a function or library available to parse this format into a date/time object.

Is Unix timestamp in GMT?

Technically, no. Even though epoch time is the means elapsed seconds since 1/1/70 00:00:00 the real “GMT” (UTC) is not. UTC time needed to be changed a few times to take in to account the slowing speed of the rotating earth.

How do you handle dates in API?

So correct ISO-8601 variants to use in URLs are YYYY-MM-DDThhmmssZ and YYYY-MM-DDThhmmss.

Check this article for the 5 laws of API dates and times HERE:

  1. Law #1: Use ISO-8601 for your dates.
  2. Law #2: Accept any timezone.
  3. Law #3: Store it in UTC.
  4. Law #4: Return it in UTC.
  5. Law #5: Don’t use time if you don’t need it.
