![]() ![]() The irony is i probably would have never found out that the last second of Jwas 23:59:60 if i wouldn't have bought. And timing isn't the easiest problem to solve, especially in a world where GPS has to take into account Einstein's theory of relativity and leap seconds have to be added from time to time to keep UTC (Coordinated Universal Time) in sync with solar time. In my opinion this is the most reasonably precise measuring standard ever. So i bought it and turned it into a single-serving website which shows, you guessed it, the current time in ms. I then checked with my hosting provider and it turned out this incredibly simple domain was available. My ISP's page popped up telling me there is no such page. ![]() I couldn't believe there isn't a site that does such a simple thing. The funniest result i saw was telling me the local time in Millis, Massachusetts. There was nothing like it in the search results. Since a program was already running, rather than just inspecting Java's System.currentTimeMillis() or running a program that shows it to me, i figured i'll open a web page that shows it. Why 1970 you ask? It's just a convention: it was the roundest most recent year to the point in time people actually started thinking about a universal measure of time.Īs i was debugging i needed something to tell me what the current time in ms is. This number has to be so large that it can encompass all the time passed since midnight January 1st, 1970 but sufficiently small that it can fit into existing data structures and keep going enough time in the future. In Android you tell an alarm when to come up by passing a simple number. The "current millis" story started with me debugging my Android application. More importantly, this site offers a time navigation service for human users and a time authority service for programmatic usage. You can also convert milliseconds to date & time and the other way around. This site provides the current time in milliseconds elapsed since the UNIX epoch (Jan 1, 1970) as well as in other common formats including local / UTC time comparisons. From this point of view the name “GMT” seems deprecated, but kept around for backward compatibility, traditional timezone based representation of time and sometimes legal reasons. If you were to calculate true GMT today i would see it based on its original definition of 1 second = 1/86400 days and this would for sure return a different absolute value than what UTC gives us. These 2 turning points (different definition of a second and the introduction of leap seconds) ‘forced’ GMT to be the same as UTC based on what seemed a gradual, tacit convention. In 1972 leap seconds were introduced to synchronize UTC time with solar time. UTC’s second is far more precise than GMT's original second. Unlike GMT which is based on solar time and originally calculated a second as a fraction of the time it takes for the Earth to make a full rotation around its axis, UTC calculates a second as “the duration of 9192631770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom”. UTC essentially appeared in 1960, GMT being the ‘main thing’ until then. In Swift, there are times when using a specific element of the language is more efficient than it's equivalent element in Python.Literature and history are a bit ambiguous. Peryton will be developed to do this through a process called Flow_Analysis, that determines the connections between functions, classes, objects and other parts of a program. ![]() However, one can theoretically infer from the structure of a function or program if a variable has the need for being protected. Where changing the let constant causes an error. In Swift, you can declare variables and constants: Fortunately, Peryton handles this issue by type-testing the input of functions, as well as object attributes. The first and foremost one, is the lack of type safe practices in Python, where you do not specify the type being passed into a function and the type being returned. Transpiling Python to Swift does raise a number of issues in the process. You can convert your favorite Python modules/documents to Swift code to use in your IOS/ OS X applications.You can make use of the Swift language without having to learn it's syntax, rules etc.You can write IOS/OS X applications use Python.The major advantages of using Peryton are: It can accept native Python code, parse it, and translate that code to the equivalent code in swift. Peryton, named after the mythological deer that has the wings of a bird, is a Python to Swift Transpiler. ![]()
