![]() Now returns an instance of the current time whereas. The only difference between them is that. This is a method that returns the number of milliseconds elapsed since 1970 and the time at which the method was called. It returns the instant of time that has occurred when it was called.įor more info on what is an instant of time, see here – This is the method I have used the most in the guide and expect that those who did not know about it would have understood it by now. Weekday returns number (position of day in the week starting from Sunday). This block returns the quantity of the given measure from the given instant. NOTE: In AppInventor you need to use Clock1.Now block, not SystemTime, for all the following examples: e.g. This block makes an instant from time combining the user inputs of year, month, day, hour, minute and seconds. ![]() The make instant from millis block makes an instant of time from the specified milliseconds calculated since 1970.įor your information a year has 3.154e+10 milliseconds. TO clear the usage of this method, I have just complicated stuff a bit! Make Instant makes an instant of the text specified in the format MM/dd/YYYY hh:mm:ss or MM/dd/YYYY hh:mm. The make date method takes in an input of year, month and date and forms an instant from the given data. This method simply returns the hour of the day of the specified instance. The get Millis block is used to get the milliseconds occurred between 1970 and the specified instance.Īnd this is the answer to why we had received 18598 days in the start. Here there is no option for specifying the format of the output and always returns time in the format – hh:mm:ss aįor more info on all possible time formats, have a look at this link. This block is used to format time in a particular instance. It also allows us to format the date along with the time in the given instance. This block is an add on to the Format Date block. We can separate the year, date and time by a comma (,), a slash (/) or a hyphen (-). These are some formats the pattern accepts. The format date block is useful when we want to return an instant into a properly formatted date. Remember: All duration parameters accept number as milliseconds.Īll these blocks have already been used in explanation of the “add” blocks, please refer them. They can accept milliseconds and give an output of seconds, minutes, hours, days and weeks. The Duration to blocks can process milliseconds to the amount of the time mentioned on them. With the help of this block, we can get the duration between two instances in milliseconds. This is a simple method and just returns the day of the month in the given instance. ![]() Here duration accepts milliseconds, so using 5000 milliseconds resulted in 5 seconds being added. I had to use a variable as 2 Do It’s in a second isn’t possible For now, it is important to notice that when we added 1 to the days, it worked! How to use this blocks and why does the clock1.now return 18598 days, will be explained later in the guide. Under the add method, we can add the following quantities. ![]() This method is used to add the amount of time specified to the given instance of time. Note: After executing all the blocks in the event is when the next interval begins. This is called every time the timer interval is completed. There is only 1 event for this component that is the. Note: The clock starts to leg when the interval is set to a very small value such as 10 milliseconds. With this property we can specify the interval (in milliseconds) between each time the click.timer event is called. Note: If the property is set to true in the designer, then the clock fill automatically fire as soon as the screen initizalizes. When you want the clock to run it’s timer, then you have to set it to true. This is a boolean property, i.e it accepts only true or false. If you wish the clock to run even if the application is not the active screen, i.e the user is using some other application. This is a Boolean property, i.e it accepts only true or false. Here, I will explain all the blocks associated to the clock component and a few sample projects which use the clock. ![]() I have made a basic guide on how to use the clock component. ![]()
