问题 I want to get a table of results showing the dates that X has entries SELECT count(*), date_column FROM myTable WHERE X GROUP BY date_column ORDER BY date_column DESC This works, but I would also like to see the dates where X does not have entries, in my use case this would be intermediary dates. So for instance 2013-3-10 would be in the results, but the next date would be 2013-3-5, yet I need my result to also return the days where count = 0, so in this case, the 6th, 7th, 8th and 9th how

问题 I'm using SSRS 2005 and I need to convert time from a serial unix time like 3412.254263 to a duration like 166:12:35 where the second format is HH:MM:SS. All .NET code should work, but I can't find any function that does not include the date or does not treat the result as a duration. Any help would be appreciated! 回答1: Public Shared Function formatSeconds(ByVal seconds As Double) As String Dim ts As TimeSpan = TimeSpan.FromSeconds(seconds) Return String.Format("{0:00}:{1:00}:{2:00}", Math

问题 I have a timestamp string as follows: String build_time=2017-11-20T21:27:03Z I want to convert it into epoch time in milliseconds as per the PST time zone such that my result is: long build_time_ms=1511299623000 How can I do this? 回答1: You can achieve this using java's java.time.* package. Below is working script and output from running groovy via docker. I haven't tried this within Jenkins though, and script may require adding appropriate def statements to avoid pipeline serialization issues

问题 In my MySQL database I have dates going back to the mid 1700s which I need to convert somehow to ints in a format similar to Unix time. The value of the int isn't important, so long as I can take a date from either my database or from user input and generate the same int. I need to use MySQL to generate the int on the database side, and python to transform the date from the user. Normally, the UNIX_TIMESTAMP function, would accomplish this in MySQL, but for dates before 1970, it always

问题 How to convert epoch like 1413225446.92000 to ZonedDateTime in java? The code given expects long value hence this will throw NumberFormatException for the value given above. ZonedDateTime.ofInstant(Instant.ofEpochMilli(Long.parseLong(dateInMillis)), ZoneId.of(TIME_ZONE_PST)); 回答1: Basil Bourque’s answer is a good one. Taking out the nanoseconds from the fractional part into an integer for nanoseconds may entail a pitfall or two. I suggest: String dateInMillis = "1413225446.92000"; String[]

问题 The code below: import java.sql.Date; import java.text.DateFormat; import java.text.SimpleDateFormat; public class FooMain { private static final DateFormat DF = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'"); public static void main(String args[]) { System.out.println(DF.format(new Date(0))); } } prints out: 1970-01-01T01:00Z Should'nt it have been 1970-01-01T00:00Z instead? I understand that Unix Epoch time is always unambiguous and we don't have to worry about timezones, but here's my

问题 I have been trying for several months to create a simple SNTP single Client/Server based on RFC5905. Finally I manage to make it work at least I think it works correctly, but when I tried to test my code against a real NTP server (e.g. 0.se.pool.ntp.org:123) the timestamps that I am receiving need to be recalculated. I have tried several different approaches but no matter for 3 days now but no matter what I tried nothing yet. Does anybody know how to convert the NTP timestamp to Unix epoch

问题 I have written below code which is running, and giving output. But I'm not sure It's a right one. SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); Date date = new Date(); sdf.setTimeZone(TimeZone.getTimeZone("GMT-7")); String value = sdf.format(date); System.out.println(value); Date date2 = sdf.parse(value); long result = date2.getTime(); System.out.println(result); return result; The above code what I'm trying is, I just need to get the current time of GMT time zone and

问题 How can one convert a serial date number, representing the number of days since epoch (1970), to the corresponding date string? I have seen multiple posts showing how to go from string to date number, but I haven't been able to find any posts on how to do the reverse. For example, 15951 corresponds to "2013-09-02" . >>> import datetime >>> (datetime.datetime(2013, 9, 2) - datetime.datetime(1970,1,1)).days + 1 15951 (The + 1 because whatever generated these date numbers followed the convention
