问题 I'm looking for a way to convert decimal hours to HH:MM:SS For instance, as input: 4.927778 hours Desired output: 04:55:40 回答1: You can try something like below dh <- 4.927778 strftime(as.POSIXct(dh * 60 * 60, origin = Sys.Date(), tz = "GMT"), format = "%H:%M:%S") ## [1] "04:55:40" 回答2: You should be able to get an idea of what you need to do - a <- "4.927778 hours" a <- as.numeric(gsub(x = a,pattern = " hours", replacement = "")) h <- a%/% 1 m <- ((a%% 1)*60) %/% 1 s <- round((((a%% 1)*60) %

问题 I'm storing messages from an amazon cloud and ordering them by their timestamp in a sorted map. I am parsing the timestamp from the cloud with the following code: Date timestamp = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSS'Z'", Locale.ENGLISH).parse(time); and then I am storing in them in a sorted map with the key being the date. The issue is that the date only comes down to seconds precision. I can have several messages sent in 1 second, so I need them to be ordered with millisecond

问题 I'm looking to create a PHP code snippet that I would add to my functions.php file but I'm not sure how to proceed. Someone asked the same question 2 years ago (Woocommerce - disable certain shipping methods based on time of day) but finally opted for a plugin that does that. I already use add-ons for detailed delivery options and I don't want to change or add another one just for this simple function if something can be done easily with php. So I'm looking to disable a shipping method if the

问题 This question already has answers here : How do I find the time difference between two datetime objects in python? (17 answers) Closed 5 years ago . I have two date time objects like this a = first date time object b = second date time object And then c = a - b Now I want to compare c and check if the difference was greater than 3 hours, so I have a time object called three_hours three_hours = datetime.time(3,0) if c >= three_hours: #do stuff but I get an error saying cannot compare datetime

问题 Is there ever a way possible to get the actual creation / modification time of the file being uploaded, using JavaScript? As for PHP, using filectime() and filemtime() , it only shows the date / time the file is uploaded, and not the time the file is actually created / modified on the source. In short, what I want is to check the m-time of a file before/during/after upload (where-ever possible) and decide whether or not to store the file on the server, and report the same back to the client.

问题 This is a follow up to a question asked previously (Filter for events that occur within a time range of event "A" in r). Since the original post was answered correctly I decided to start a new question. If this is improper let me know. Quick recap. I have event data with a second value. I wanted to filter all B events that came 5 seconds prior to all A events. The issue I've run into is that the data is split into periods and the seconds restart. I didn't think this would be an issue as the
