问题 This question already has answers here : Convert a date format in epoch (5 answers) Closed 3 years ago . Is there a way to convert a given Date String into Milliseconds ( Epoch Long format) in java? Example : I want to convert public static final String date = "04/28/2016"; into milliseconds (epoch). 回答1: The getTime() method of the Date class returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. 回答2: You can simply parse it to java.util.Date

问题 This question already has answers here : Convert string date to timestamp in Python (13 answers) Closed 9 months ago . I am using tweepy to get a tweet. I am trying to send this tweet over Slack. Tweepy gives the time in a strange format, and Slack requires the time in epoch. for i in tweets: created=(i.created_at) print(created) print(created.strftime('%s')) This returns 2017-01-17 14:36:26 Traceback (most recent call last): File "C:\Users\Administrator\Desktop\slackbot3\run.py", line 287,

SimpleDateFormat always returns 1970.01.17 with wrong timezone

问题 I have been using Processing 3.0, and I am trying to print a simple timestamp when my Arduino outputs certain values, but it is not working. I tried to use SimpleDateFormat, but it always returns 1970.01.17 17:48:35 GMT , rather than the actual time. Below is the MVCE: void setup () { SimpleDateFormat format = new SimpleDateFormat ("yyyy.MM.dd HH:mm:ss z"); format.setTimeZone (TimeZone.getDefault()); long timestamp = getTimeNow(); println(format.format(new Date(timestamp))); println(timestamp

How do I convert epoch time to normal time in Perl?

一笑奈何 提交于 2019-12-07 03:52:08
问题 I am attempting to write a Perl script that parses a log where on each line the second value is the date. The script takes in three arguments: the input log file, the start time, and the end time. The start and end time are used to parse out a certain value on each line that that falls between those two times. But to properly run this I am converting the start and end time to epoch time. The problem I am having is that to convert the loops 'i' value back to normal time to compare against the

“致"高级"工程师(BUG工程师) 一颗折腾的心💗 原创不易,点个赞,点个关注,支持支持!! 1 replication 如图所示,同一个 partition 可能会有多个 replica(对应 server.properties 配置中的 default.replication.factor=N)。 没有 replica 的情况下,一旦 broker 宕机,其上所有 patition 的数据都不可被消 费,同时 producer 也不能再将数据存于其上的 patition。 引入replication 之后,同一个 partition 可能会有多个 replica,而这时需要在这些 replica 之间选出一个 leader,producer 和 consumer 只与这个 leader 交互,其它 replica 作为 follower 从 leader 中复制数据。 Kafka 分配 Replica 的算法如下: 将所有 broker(假设共 n 个 broker)和待分配的 partition 排序 将第 i 个 partition 分配到第(i mod n)个 broker 上 将第 i 个 partition 的第 j 个 replica 分配到第((i + j) mode n)个 broker上 2 leader failover 当 partition 对应的

问题 I am facing some problems in a cross platform program : when I open a python shell in Linux and in Windows, I don't get the same time from the Epoch. In Linux, I tried to do dpkg-reconfigure tzdata . Currently, in linux I get that avec the dpkg-reconfigure tzdata : Current default time zone: 'Europe/London' Local time is now: Mon May 30 10:29:52 BST 2011. Universal Time is now: Mon May 30 09:29:52 UTC 2011. Then, in the python console, I create this script : import time print time.tzname,

Converting from an integer epoch time value to local time

↘锁芯ラ 提交于 2019-12-06 14:46:34
问题 I've been stuck on converting from an integer epoch time value to a local time. I currently have the time since epoch stored in an integer variable, and I need a way to convert that to local time. I have tried passing it into localtime but it doesn't seem to work. I can get localtime to work if I simply call time_t rawtime; struct tm * timeinfo; time ( &rawtime ); timeinfo = localtime ( &rawtime ); And get the rawtime directly, but I'm stuck if I want to give localtime() an integer value

Get milliseconds from epoch via HTTP

十年热恋 提交于 2019-12-05 23:00:21
I am working on a microcontroller and don't want to keep track of time with the system clock. I want to make an HTTP request to get the current time in milliseconds from the epoch (1970). I already know how to form all the requests, I just can't find a url that can return this data to me. Who offers this as an API? I don't want to make an https request. I have a site called Current Millis and theoretically infinite bandwidth. I think i can quickly write a php, say www.currentmillis.com/api/millis-since-epoch.php. Is this ok for you? UPDATE: It was infinite bandwidth but not infinite resources.

zk中使用zab协议来保证数据一致性

1zab能够保证一个全局的变更序列被顺序应用 2zab协议包含两个模式: 崩溃恢复 消息广播 Zab协议必须设计这样一个选举算法:能够确保提交已经被leader提交的事务proposal,同时丢弃被跳过的事务Proposal 数据同步 所有运行服务器,要不成为leader,要不成为follower和leader进行同步 在zab协议的事务编号zxid,是一个64位数字,低32位是一个简单的单调递增计数器,高32位是代表leader周期epoch的编号 zab系统模型 进程组,状态有up状态,也有down状态,当集群中存在过半up状态组成的进行后,就可以进行正常的消息广播了 使用pi,pj分别表示进程组[]中两个不同进程,使用cij表示进程pi和pj之间的网络通信通道,满足如下两个基本条件 完整性 如何进程pj收到了来自pi的消息m,那么进程pi一定确实发送了消息m 前置性, 如果进程pj收到了消息m,那么存在这样的消息m`,如果m`是m的前置消息,那么pj务必先接收到消息m`,然后再接收到m,这样才能保证消息的顺序 主进程周期 为了保证每次广播出来的消息是一致的,必须确保zab协议只有在充分完成崩溃恢复阶段之后,新的主进程才可以开始生成新的事务消息广播。 事务, 各个进程都存在一个类似于transactions(v,z)这样的函数调用,来实现主进程对状态变更的广播,v表示事务内容
