29 wrz 2014 · I have a DB that stores dates as datetime with UTC offset. How do I convert these dates from UTC to say CET in a select statement? And is there are some kind of syntax sugar that takes care of the whole daylight autumn/winter and springs/summer offset thing? EDIT: I've found this library on CodePlex useful: DateTimeUtil
24 lip 2017 · I'm having trouble converting a date between CET and UTC when the date is in daylight savings. It's an hour different to what I expect: >>> print from_cet_to_utc(year=2017, month=7, day=24, hour=10, minute=30) 2017-07-24T09:30Z 2017-07-24T08:30Z # expected CET is an hour ahead of UTC and in summertime is 2 hours ahead.
49. An option available since Python 3.6: datetime.astimezone(tz=None) can be used to get an aware datetime object representing local time (docs). This can then easily be converted to UTC. from datetime import datetime, timezone. s = "2008-09-17 14:02:00".
27 mar 2017 · 6. I want to convert a given date time (which is a utc date time) to the corresponding date time in CET with a proper mapping of the european summer/winter time switch (daylight saving time). I managed to to the opposite (CET to UTC) using java.time: ZonedDateTime cetTimeZoned = ZonedDateTime.of(timeInCet, ZoneId.of("CET"));
19 wrz 2012 · 4. To convert any TimeZone DateTime string to UTC, one could use PARSE_TIMESTAMP using the supported TIMESTAMP Formats in BigQuery. For example to convert IST (Indian Standard Time) string to UTC, use the following: Here PARSE_TIMESTAMP parses the IST string to a UTC TIMESTAMP (not string).
21 lis 2018 · The UTC timestamp on the jsfiddle link is incorrect. Actually your "Local timestamp" is the UTC timestamp and your "UTC timestamp" is the # of seconds between epoch UTC and your local time, which isn't really meaningful. Date.getTime automatically returns a UTC timestamp. –
23 kwi 2010 · You can chain these to do conversions: SELECT YourOriginalDateTime AT TIME ZONE 'Pacific Standard Time' AT TIME ZONE 'UTC'. Or, this would work as well: SELECT SWITCHOFFSET(YourOriginalDateTime AT TIME ZONE 'Pacific Standard Time', '+00:00') Either of these will interpret the input in Pacific time, properly account for whether or not DST is in ...
30 lip 2009 · I tend to lean towards using DateTimeOffset for all date-time storage that isn't related to a local event (ie: meeting/party, etc, 12pm-3pm at the museum). To get the current DTO as UTC: DECLARE @utcNow DATETIMEOFFSET = CONVERT(DATETIMEOFFSET, SYSUTCDATETIME()) DECLARE @utcToday DATE = CONVERT(DATE, @utcNow);
11 kwi 2013 · For Python 3, use datetime.now(timezone.utc) (the 2.x solution will technically work, but has a giant warning in the 3.x docs): from datetime import datetime, timezone datetime.now(timezone.utc) For your purposes when you need to calculate an amount of time spent between two dates all that you need is to subtract end and start dates.
21 lip 2009 · The following will return the current UTC date as just that -- a DATE. CAST(sys_extract_utc(SYSTIMESTAMP) AS DATE) I often store dates like this, usually with the field name ending in _UTC to make it clear for the developer. This allows me to avoid the complexity of time zones until last-minute conversion by the user's client.
