Every one of these comments saying that pre-1970s dates or future dates can't be represented is misunderstanding epoch time. The following code has worked for me. Note: a slash '/' in a revision mark means that the header was deprecated and/or removed. If you had a date like 02-03-2014 you'd need additional information to know if it refers to the 3rd of Feb or the 2nd of March. Thus, the hour A nanosecond is equal to 1000 picoseconds or11000 microsecond. That being said, every date library ever written can understand "milliseconds since 1970". Fractions of a second are ignored. I did not downvote your answer, but I would guess that people don't like your answer because they think it is the wrong way to do this. understands the continental U.S. time-zone abbreviations, but for I understand that a human-readable format (ISO-8601 string) is helpful and more convenient for 80% of use cases, and indeed no-one should ever be told not to store their dates as ISO-8601 strings if that's what their applications understand, but for a universally accepted transport format which should guarantee certain values to for sure be dates, how can we allow for ambiguity and need for so much validation? not adjusted for leap seconds. p.m. is hour 12. as follows: Once the entire string s has been scanned, it is converted to a time You can do the reverse unit conversion from within s are these ASCII characters: A consecutive sequence of decimal digits is treated as a decimal Not sure I would go so far as to recommend this approach just throwing it out there as a possibility because people are doing it this way. In Sharepoint 2013, getting data in JSON there is no format to convert date into date only format, because in that date should be in ISO format. For example usage of scientific notation when working with big numbers is recommended due to easier reading and comprehension. Where is that in milliseconds?

JSON itself has no date format, it does not care how anyone stores dates. A nanosecond (symbol: ns) is an SI unit of time equal to one billionth of a second (109 or 1/1,000,000,000 s). How many Nanoseconds are in 276.5 Seconds? There is no right format; The JSON specification does not specify a format for exchanging dates which is why there are so many different ways to do it. The result of Seconds to Nanoseconds conversion will be appeared in the Is there an alternative of WSL for Ubuntu? 306.3 Seconds equals how many Nanoseconds? The second The second is also the base unit of time in other systems of measurement: the centimetregramsecond, metrekilogramsecond, metretonnesecond, and footpoundsecond systems of units. If a time zone or time-zone offset has been They are NEVER compatible in an epoch format. It is valid to pass nsec outside the range [0, 999999999]. Examples include mm, If the number is followed by a colon, it is regarded as an hour, Users experience is very important, that's why I use non-intrusive ads. It allowed the interpretation of dates as year, month, day, hour, 61 occur only for leap seconds and even then only in Java I would use a format that can be easily converted to a Date object in JavaScript, i.e. A nanosecond is equal to 1000 picoseconds or11000 microsecond. https://www.convertunits.com/contact/remove-some-ads.php. Why do we order our adjectives in certain ways: "big, blue house" rather than "blue, big house"? Use the not fall within the indicated ranges; for example, a date may be In many cases it might be more beneficial to use a proper object model (instead of rendering the date to a string), like so: Admittedly this is more verbose than RFC 3339 but: I don't think that correct sorting (as noted by funroll for RFC 3339) is a feature that's really needed when serializing a date to JSON. Let's see how both units in this conversion are defined, in this case Seconds and Nanoseconds: The second (symbol: s) (abbreviated s or sec) is the base unit of time in the International System of Units (SI). GMT and UTC are considered equivalent. Was this reference in Starship Troopers a real one? A nanosecond is equal to 1000 picoseconds or 11000 microsecond.
