unix-timestamp

问题 I'm trying to get the unix time from a timestamp field in milliseconds (13 digits) but currently it returns in seconds (10 digits). scala> var df = Seq("2017-01-18 11:00:00.000", "2017-01-18 11:00:00.123", "2017-01-18 11:00:00.882", "2017-01-18 11:00:02.432").toDF() df: org.apache.spark.sql.DataFrame = [value: string] scala> df = df.selectExpr("value timeString", "cast(value as timestamp) time") df: org.apache.spark.sql.DataFrame = [timeString: string, time: timestamp] scala> df = df

问题 I have a Django class as follows: class MyModel(models.Model): my_int = models.IntegerField(null=True, blank=True,) created_ts = models.DateTimeField(default=datetime.utcnow, editable=False) When I run the following queryset, I get an error: >>> from django.db.models import Max, F, Func >>> MyModel.objects.all().aggregate(Max(Func(F('created_ts'), function='UNIX_TIMESTAMP'))) Traceback (most recent call last): File "<console>", line 1, in <module> File "MyVirtualEnv/lib/python2.7/site

问题 Assume a given variable, it is containing a UNIX time-stamp, but whether it is in seconds or milliseconds format is unknown, I want to assign to a variable which is in seconds format For Example: unknown = 1398494489444 # This is millisecond t = ??? Updated: I understand it is not possible to tell without giving some limitations, so here is it current_ts - 86400 * 365 < unknown < current_ts Assume current_ts = current unix timestamp 回答1: If you convert the maximum timestamp values with x

问题 Is there a good way to parse milliseconds since epoch (ex. 1486252500000 13 digits) formatted time into a human readable format? 回答1: DateTime does have a named constructor for millisecond since epoch https://api.dartlang.org/stable/1.24.2/dart-core/DateTime/DateTime.fromMillisecondsSinceEpoch.html DateTime date = new DateTime.fromMillisecondsSinceEpoch(1486252500000) If you want to convert it to human readable string, you can use intl package with the DateFormat class import "package:intl
