timestamp

问题 This is my elasticsearch query that intends to filter data between 11 pm and 12 pm on the day 2015.08.04. But it doesn't filter and gives many errors. "query" : {"range" : {"@timestamp" : {"gt" : "2015-08-04 11:00:00", "lt" : "2015-08-04 12:00:00"} } } 回答1: It works with the following query { "query":{ "range":{ "@timestamp":{ "gte":"2015-08-04T11:00:00", "lt":"2015-08-04T12:00:00" } } } } 来源： https://stackoverflow.com/questions/32619909/elasticsearch-query-based-on-timestamp

问题 I have an application with a VideoView in it, I set a video to play in the VideoView. At some point while the video is playing it will get paused. Then after it is paused for some time it will begin to play the video again, but seek forward to the point that the video would be at if it had not been paused. So for instance Video starts playing Video paused at 6 seconds video stays paused for 10 seconds Video starts playing again <--- at this point I want the video to start playing at the 16

问题 We are having a debate about the best way to store a timestamp in postgres. Currently all time stamps are stored as +00 and we have a timezone associated with each client. We look up the timezone and convert the time that something happened which increases complexity as we need to do more joins and a more complex query. Another method is connecting to Postgres and setting the timezone of the connection and it changes all the times to be that timezone. My problem with this is that in ANZ there

问题 I created a table in Redshift: create table myTable ( dateTime TIMESTAMP NOT NULL, ... ); However, when I try to insert a record that contains a dateTime of, I get an error from stl_load_errors . 20080215 04:05:06.789 Since I took this timestamp from the docs, I would've expected it to have worked. The error logs from Redshift show: Invalid timestamp format or value [YYYY-MM-DD HH24:MI:SS] However, I'd like to include 3 extra seconds, example: 2015-02-01 15:49:35.123 . How do I need to modify

问题 Is there a way to retrieve the time an object was created at? 回答1: Not generally but you can do it for objects you create yourself via R> df <- data.frame(a=sample(LETTERS[1:5],10,TRUE),b=runif(10)) R> attr(df, "createdAt") <- Sys.time() R> df a b 1 B 0.8437021 2 D 0.8683446 3 B 0.5194791 4 B 0.0480405 5 B 0.5604978 6 C 0.1938154 7 A 0.1451077 8 D 0.1785405 9 C 0.3937795 10 B 0.2874135 R> str(df) 'data.frame': 10 obs. of 2 variables: $ a: Factor w/ 4 levels "A","B","C","D": 2 4 2 2 2 3 1 4 3
