This is what i'm trying to do:
I want to create a simple shell script that checks the current timezone in the UK.
i.e. BST or GMT.
I only can display the time for the current timezone the UK is in. i.e. UK is in GMT right now and I can only display that time. [TZ=GMT date]
Please note: I do not wish to permanently modify the UNIX time zone on the server (currently CET)
Based on that I need to do some calculations (which I'm fine with)
I have already searched and I cannot find anything specific to this problem. Thank you for your help
To get the date for a particular timezone, you can do:
TZ=GMT date
(Or date +%s if you want epoch format, which is also TZ independent, but altogether friendlier for calculations. ).
For what it is now, relative time I think it's as simple as:
TZ=Europe/London date
Which I think should cause your system to report BST/GMT appropriately.
If you want it to specifically report the offset, you can use the %z format specifier:
TZ=Europe/London date +"%Y%m%d %H:%M:%S %z"

I am developing a laravel application which stores GMT time in database accross the world.
Now I want user to see time in his local timezone but for this I must aware of user's local timezone which I don't.
I have user's country ISO code and using DateTimeZone::listIdentifiers method I can get the timezone but it returns array of timezones for some countries.
So is there a method or way through which I can get offset in hours between GMT +00:00 and user's local GMT time?
You need to make some request passing the timezone from client/browser to your server to get an accurate timezone.
Many countries have multiple timezones, Russia, USA, just to mention some. So country code is not enough.
Then, don't use offset, use named timezone as many timezones also have multiple offset due to daylight saving. Europe/Paris can be GMT+1 or GMT+2 and so current offset between GMT+0 now != current offset for your given timestamp.
When you have the precise city name of the timezone, then it's really simple to use it before formatting a Carbon date:
Carbon::createFromTimestamp($utcTimestamp)->tz('America/New_York')
I'm trying to change some old .asp files with vbs. Our database is going to be converted to store dates in UTC, but on webpages it should show dates and time in "Europe/Helsinki" timezone(
TimeZoneInfo.FindSystemTimeZoneById("FLE Standard Time")
in c#). How can I cast the UTC date I get from db query( the query is run in the .asp file as well and the result put into table) to correct date time using vbscript?
Just offset the UTC dates using DateAdd().
Const EETOffset = -2 'EET offset from UTC is -2 hours
Dim dbDateValue 'Assumed value from DB
Dim newDate
'... DB process to populate dbDateValue
newDate = DateAdd("h", EETOffset, dbDateValue)
Note: One problem with this approach is you will also have to compensate for EET and EEST (Eastern European Summer Time) manually based on the time of year. Which is also more difficult when you take into consideration some places don't use it and use EET all year round instead.
See EET – Eastern European Time (Standard Time).
Depending on the RDMS you are using you should even be able to manipulate the dates before they get to the page as part of the initial query.

I'm importing SQL data into Spotfire Analyst. All of the date and time fields are in the form of a Unix timestamp. What's the best way to convert this into an actual date format that I can manipulate in Spotfire?
Utilizing a calculated column you can calculate the datetime based on the UNIX epoch.
We simply add our seconds to the DateTime of the UNIX epoch (JAN 01 1970 00:00:00 UTC) to get the result. Below is an example of the UNIX time when I started writing this post.
DateAdd("second",1429733486,DateTime(1970,1,1,0,0,0,0))
The below is what should work for you:
DateAdd("second",[UNIX_TIMESTAMP_COLUMN],DateTime(1970,1,1,0,0,0,0))
Keep in mind these dates produced will be in the UTC timezone as per the JAN 1 1970 epoch. If you need them in your local time zone you may have to adjust accordingly with further DateAdd functions adding/subtracting time as per current conversions. Also, if you observe daylight savings time you may need to add some extra case logic to handle that as well.
Please let me know if you have any questions or need further clarification.
In 7.0 and later you can use
FromEpohTimeSeconds([UNIXDATE])
or
FromEpohTimeMilliseconds([UNIXDATE])
In TeamCity 6.0.3, is there a way to set the time format to show 12-hour time format instead of 24-hour time format? For example, I would like times to show 2:00 PM instead of 14:00. I found the user-specific setting to show time in the user's timezone but this still displays time in 24-hour format.
I'm afraid, we don't provide such a possibility.
