Is there a Hijri Date to Georgian Date Conv and vice versa, which is reliable?

北城以北 提交于 2020-05-15 06:45:31
问题 I am looking for a Library that can give me the needed tools, to calculate for example how many days it is from now, to a specific Date AND that I can use to determine whether I am in a specific time period (eg. Muharram +- 5days) or not I have been looking for over 10hours now, and the best things I found were the "HijrahDate" library "java.time.chrono.HijrahDate" and something called "Joda Date", which I had difficulties to use. If anyone can help me with that, it would be much appreciated.

How to return current date in a different timezone in PostgreSQL

大憨熊 提交于 2020-05-14 18:06:09
问题 I'm working on an application which uses Eastern time with a database set to Pacific time. This has been causing some issues, but we're told that it can't be any other way, so we just have to work around it. Anyway, one of the things I'm having trouble with is getting today's date. Since the database is in Pacific, if I ask for today's date using current_date at, say, 1AM, it'll give me yesterday's date. I've tried setting timezone and adding/subtracting intervals, but it never seems to work

Using JS server time instead of client time to avoid this behavior where users can manipulate results by changing their local machine clock

我与影子孤独终老i 提交于 2020-05-14 03:52:46
问题 Expected behavior Show users a random value (color) from the arr array on each refresh. Each day a different file ( file-1.json , file-2.json , etc) should be loaded into arr . This should reset at 00:00 UTC server time. Only values from that day's associated file should be displayed. Unexpected behavior All works well, until users change the clock on their local machines/phones. Then they can effectively see future & past values as well. Date/time can be manipulated client-side, which

How to check if two series of dates overlap and determine the first date that it occurs?

问题 How to check if two series of dates overlap and determine the first date that it occurs? Imagine that I've created two events in Google Calendar. One of them in Date1 and repeating every X days; the other in Date2 and repeating every Y days. What would be the best algorithm to determine if the two series will overlap someday, and find the first date that it would happen? Example 1: Date1 = Feb-15, 2016 X = 14 (repeat every 14 days) Date2 = Feb-22, 2016 Y = 21 (repeat every 21 days) Result:
