dst

This question already has an answer here: Is a specific timezone using DST right now? 1 answer We have a server that runs on GMT time. I need to write a Python script that determines if it's currently (at this very second) Daylight Savings Time (DST) in Los Angeles, CA. How can I accomplish this? I took a look at pytz and time, but I can't figure it out. I realize that I could create some logic such as comparing the current time in LA to GMT time, but it would be a lot cleaner if I could use a standard library instead. Thanks Edit: Here's some sample code of me setting up the timezone: from

In PHP, you can tell if a given date is during the Daylight Savings Time period by using something like this: $isDST = date("I", $myDate); // 1 or 0 The problem is that this only tells you whether that one point in time is in DST. Is there a reliable way to check whether DST is in effect at any time in that timezone? Edit to clarify: Brisbane, Australia does not observe daylight savings at any time of the year. All year around, it is GMT+10. Sydney, Australia does, from October to March when it changes from GMT+10 to GMT+11. I'm wondering if there would be some existing method, or a way to

What's the best way to convert datetimes between local time and UTC in C/C++? By "datetime", I mean some time representation that contains date and time-of-day. I'll be happy with time_t , struct tm , or any other representation that makes it possible. My platform is Linux. Here's the specific problem I'm trying to solve: I get a pair of values containing a julian date and a number of seconds into the day. Those values are in GMT. I need to convert that to a local-timezone "YYYYMMDDHHMMSS" value. I know how to convert the julian date to Y-M-D, and obviously it is easy to convert seconds into

In one of the Oracle database server it is showing "+01:00" when I fire the "Select dbtimezone from dual" does that mean in summer the clock will shift one hour ahead ?. In another server it is showing "+00:00" does that mean the database server setting is GMT ? but I am using the sysdate in oracle pl/sql. Client is saying the Aix server is on DST so would that mean the DB server will adopt the AIX server setting after clock change ? How to fix this problem. Answer is: It depends. In total your database has three time zones Your seesion time zone: SESSIONTIMEZONE This you can change by ALTER

I would like to use R for time series analysis. I want to make a time-series model and use functions from the packages timeDate and forecast. I have intraday data in the CET time zone (15 minutes data, 4 data points per hour). On March 31st daylight savings time is implemented and I am missing 4 data points of the 96 that I usually have. On October 28th I have 4 data points too many as time is switched back. For my time series model I always need 96 data points, as otherwise the intraday seasonality gets messed up. Do you have any experiences with this? Do you know an R function or a package
