P.S. For example, moment().format("MMMMD") will display April for MMMM, that is the current month and current date for D. So the output is April16.With format, it tries to convert the units given to the corresponding display of date… Just add 2 days. For example, moment().format("MMMMD") will display April for MMMM, that is the current month and current date for D. So the output is April16.With format, it tries to convert the units given to the corresponding display of date… All you can do is to use the built-in methods, and compose the date as you want using them.

Get-Date can format the date and time in several .NET and UNIX formats. The second, formatDate, converts date objects into strings, with whatever formatting you specify. They may tweak results of “artificial tests” compared to “normal usage”, especially when we benchmark something very small, such as how an operator works, or a built-in function. The new Date constructor uses the local time zone. It returns 2-digit year sometimes. A problem with defining a complete custom format specifier that includes the millisecond component of a date and time is that it defines a hard-coded format that may not correspond to the arrangement of time elements in the application's current culture. There are hundreds of timezones in our world. It’s a lightweight numeric representation of a date. By using our site, you 2. getDay(): Returns the day of the week.

All the methods above return the components relative to the local time zone. Convert time into date object and store it into new variable date. For instance, if today is 20th, then getDateAgo(new Date(), 1) should be 19th and getDateAgo(new Date(), 2) should be 18th. The above shown date time is the default format. Imagine that at the time of running bench(diffSubtract) CPU was doing something in parallel, and it was taking resources. This returns the number of milliseconds since the Unix Epoch of the Day.js object. JavaScript, however, understands the date based on a timestamp derived from Unix time, which is a value consisting of the number of milliseconds that have passed since midnight on January 1st, 1970. The algorithm is the same as Date.parse uses, we’ll cover it later.

And then you probably won’t need microbenchmarks at all. These two do exactly the same thing, but one of them uses an explicit date.getTime() to get the date in ms, and the other one relies on a date-to-number transform. The third, getCurrentDate, returns the current time in the system time zone in a string, with the formatting specified in the first argument. For our case, functions are very simple, so we have to do it at least 100000 times. It's not so straight to change JavaScript date time format.
