timezone-offset

So I have a site with a comments feature where the timestamp of the comment is stored in a MySQL database. From what I understand, the timestamp is converted to UTC when stored, then converted back to the default timezone when retrieved. In my case, my server is in the Central Daylight Time timezone (CDT). I have a plan to get the timezone from each user via entry form. I just wanted to know how to convert the TIMESTAMP value into the user's timezone. First, would I convert from UTC to local timezone? Or CDT to local timezone? Secondly, how would I go about doing that in PHP? Would I just do:

In Java 8, I want to convert a datetime from UTC to ACST (UTC+9:30). input -> 2014-09-14T17:00:00+00:00 output-> 2014-09-15 02:30:00 String isoDateTime = "2014-09-14T17:00:00+00:00"; LocalDateTime fromIsoDate = LocalDateTime.parse(isoDateTime, DateTimeFormatter.ISO_OFFSET_DATE_TIME); ZoneOffset offset = ZoneOffset.of("+09:30"); OffsetDateTime acst = OffsetDateTime.of(fromIsoDate, offset); System.out.println(acst.toString()); // 2014-09-14T17:00+09:30 System.out.println(acst.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME)); // 2014-09-14T17:00:00+09:30 Why is the offset not performed? Try:

From git I can get the timestamp: "2011-10-04 12:58:36 -0600" but is there any way to show it as: "2011-10-04 06:58:36" So all I want is to get rid of the -0600 timezone offset. How can I do this? Thanks. Lazy Badger If you ask about git log, you can try and select most correct form from: git log --date={relative,local,default,iso,rfc} --date=local seems to be the best candidate. To make this permanent, use git config --global log.date local . git log --date=local Does the trick. git config --global log.date local Christian TZ=UTC git log --date=local in order to get non-local-timezone one

I am trying to convert Twitter datetime to a local iso-string (for prettyDate) now for 2 days. I'm just not getting the local time right.. im using the following function: function getLocalISOTime(twDate) { var d = new Date(twDate); var utcd = Date.UTC(d.getFullYear(), d.getMonth(), d.getDate(), d.getHours(), d.getMinutes(), d.getSeconds(), d.getMilliseconds()); // obtain local UTC offset and convert to msec localOffset = d.getTimezoneOffset() * 60000; var newdate = new Date(utcd + localOffset); return newdate.toISOString().replace(".000", ""); } in newdate everything is ok but the toISOString

A head scratcher for you. I am grabbing geo IP data from IPInfoDB 's API and it returns a timezone offset from UTC including DST (if currently reflected). For example, I live in EST (-5) and currently it's DST, so the geo IP API returns ( -04:00 ) as the offset. This is wonderful since DST is a freaking headache. But to my surprise, it caused another headache. I load this data in PHP to be passed via AJAX to the application. I would like to have the live local time of the IP address on the app. I have that all set perfectly, but I am going crazy trying to figure out how to set the PHP timezone

This question already has an answer here: Cannot parse String in ISO 8601 format, lacking colon in offset, to Java 8 Date 1 answer We try to parse the following ISO 8601 DateTime String with timezone offset: final String input = "2022-03-17T23:00:00.000+0000"; OffsetDateTime.parse(input); LocalDateTime.parse(input, DateTimeFormatter.ISO_OFFSET_DATE_TIME); Both approaches fail (which makes sense as OffsetDateTime also use the DateTimeFormatter.ISO_OFFSET_DATE_TIME ) because of the colon in the timezone offset. java.time.format.DateTimeParseException: Text '2022-03-17T23:00:00.000+0000' could
