问题 How to convert a human readable time with the format 20.12.2016 09:38:42,76 to Unix timestamps in milliseconds ? I found a lot of similar questions, but didn't found this specific question/answer. 回答1: In Python 3 this can be done in 2 steps: Convert timestring to datetime object Multiply the timestamp of the datetime object by 1000 to convert it to milliseconds. For example like this: from datetime import datetime dt_obj = datetime.strptime('20.12.2016 09:38:42,76', '%d.%m.%Y %H:%M:%S,%f')

group by month of unix timestamp field

由 那年仲夏 提交于 2019-12-03 05:44:38
I'm trying to get my code to output in the following format: january 2012 - 34 february 2012 - 23 where 34 and 23 would be a count of the total rows that fall within that month that have the id_dealership of 7. I need this to output all data for every month that an assignment was ever made. The assignments table structure is as follows: id_dealer (int) date_assigned (int) I've tried this but it does not work at all: SELECT MONTH(date_assigned), YEAR(date_assigned), COUNT(*) FROM assignments GROUP BY MONTH(date_assigned), YEAR(date_assigned) SELECT MONTH(FROM_UNIXTIME(date_assigned)), YEAR(FROM

Mysql: Convert DB from local time to UTC

由 三世轮回 提交于 2019-12-03 04:28:49
问题 I need to convert an existing (datetime fields) db from local time ut UTC. The values are stored ad datetimes on a server with time zone CET (+1) (with summertime +2). When selecting data I use UNIX_TIMESTAMP() , which magically compensates for everything, ie, time zone shift and dst (if i've read the docs right). I'm moving the db to a new server with UTC as system time. Simply subtracting -1 H won't work, as summer time is +2. Any ideas for a clever way to do this? (using sql or some script

How to represent dates before epoch as a UNIX timestamp

由 纵饮孤独 提交于 2019-12-03 01:31:16
It occurred to me that I'm not aware of a mechanism to store dates before 1970 jan. 1 as Unix timestamps. Since that date is the Unix "epoch" this isn't much of a surprise. But - even though it's not designed for that - I still wish to store dates in the far past in Unix format. I need this for reasons. So my question is: how would one go about making unix-timestamps contain "invalid" but still working dates? Would storing a negative amount of seconds work? Can we even store negative amounts of seconds in a unix-timestamp? I mean isn't it unsigned? Also if I'm correct then I could only store

问题 I had two datetime strings like below... 2014-09-03T02:23:09Z and 2014-09-03T03:24:57Z Now, I have to assign the two datetimes to some variables and compare them, like this: d1=2014-09-03T02:23:09Z d2=2014-09-03T03:24:57Z if (d1 < d2 ) I browsed many websites but couldn't find a solution. I tried the approach below but it doesn't work. #set -vx date1=`date -d "2014-09-03T04:27:23Z" +"%Y-%m-%dT%TZ"` date2=`date -d "2014-09-03T02:23:09Z" +"%Y-%m-%dT%TZ"` date3=`date -d "2014-09-03T05:23:09Z" +"
