time

问题 I'm trying to add some values from my database to a []string in Go. Some of these are timestamps. I get the error: cannot use U.Created_date (type time.Time) as type string in array element Can I convert time.Time to string ? type UsersSession struct { Userid int Timestamp time.Time Created_date time.Time } type Users struct { Name string Email string Country string Created_date time.Time Id int Hash string IP string } - var usersArray = [][]string{} rows, err := db.Query("SELECT u.id, u.hash

问题 Offtopic: I'm new to stack overflow, and I wanted to say hello! On topic: I'm generating a version 5 UUID for an application that needs randomized folder creation and deletion via a timestamp time() through my $md5_UUID = create_uuid_as_string(UUID_MD5, time."$job"); These folders are generated per run on each job, and are deleted after running. If the same UUID is somehow generated, the +-1000 jobs that are running could halt. Is there any information that I can pull from this or any

问题 I'm trying to correlate the timing information obtain from a java job and linux performance monitoring tool perf (specifically perf stat ). The timing information from java is obtained using String tstamp0 = String.valueOf(System.currentTimeMillis()); (This is essentially time in milliseconds from epoch) whereas perf gives the time the process has began and the subsequent recording only show the time elapsed. What I would like to do is, convert the timing information obtained from the perf

问题 Say I have 2 strings in the following format: "09/21 10:06AM" "09/21 10:10AM" How do I find the time difference between these strings, stored as an int? This has to be robust enough to handle situations like 10:59AM and 11:02AM (odd number of minutes in between), 11:59AM and 12:03PM (AM to PM switch) etc. No need to worry about seconds. Thanks! 回答1: I would suggest: Use Joda Time instead of the built-in API; it's much nicer. Parse into LocalDateTime values Find the difference between them

问题 So I have this piece of code that would return the current EST Date easternTime = new Date(); DateFormat format = new SimpleDateFormat("h:mm a"); format.setTimeZone(TimeZone.getTimeZone("EST")); return format.format(easternTime); let say it return x = 12:15PM I want to compare x to 3:00PM EST to see if x before or after 3:00PM EST, and/or is x between 3:00PM - 6:00PM EST. Is there a way to do this. We dont have to use java.util.date . I take solution with calendar as well 回答1: I would

问题 I have a method in my Post model that looks like this: def self.num_posted_x_days_ago(n) start_date = Time.now.midnight - n.day end_date = Time.now.midnight - (n+1).day where(created_at: start_date..end_date).count end When I run it in IRB, I get this: > Post.num_posted_x_days_ago(8) (0.3ms) SELECT COUNT(*) FROM "posts" WHERE ("posts"."created_at" BETWEEN '2015-02-27 05:00:00.000000' AND '2015-02-26 05:00:00.000000') => 0 Note that the Time on the date is 05:00:00.000000 for both the start

问题 I'm trying to make an object that handles basic time related functions. I want it so when any of the attributes (e.g. self.Time ) are referenced they are up to date. However, for some reason wx.CallLater(1000, self.Tick) doesn't seem to be updating the attributes. It will only print self.Time once, as opposed to every second (like I want it to). How would I go about getting the behavior I desire? Should I use something besides wx.CallLater(1000, self.Tick) ? Snippet : import wx, re, time,
