utc

问题 I called method: TimeZoneInfo.ConvertTimeFromUtc(DateTime.Now.ToUniversalTime(), TimeZoneInfo.FindSystemTimeZoneById("GMT Standard Time")) // UTC+0 It is returned DateTime for one hour larger than the correct DateTime. Why? How will it fix? Returned value should be equal DateTime.Now.ToUniversalTime() 回答1: UTC is equal to GMT. But currently we're in BST due to summer, which is GMT + 1. GMT Standard Time automatically adjusts for daylight savings. Use Greenwich Standard Time , rather than GMT

问题 I am writing an app that has a time slot booking system. The users can be in different timezones, thus I need to store the values in the database in UTC time. I was wondering how UTC_TIMESTAMP() is calculated in MySQL. Is it reliable? If the server timezone is in an area with daylight savings will UTC_TIMESTAMP() always behave correctly, even during time changes due to daylight savings? 回答1: UTC is always +0:00 - it ignores daylight savings, regardless of whether or not it is in effect.

问题 This is a question similar to this one. I'm really tempted to store datetimes in my app as local time rather than as UTC (which is considered a best practice). In the app I have a number of events happening, each assigned to a given location. Always when I display them to the user, I want to show the local time of the event. I.e.: ==================================================================================== Event time (with TZ) | As UTC | As local time | To be displayed | =============

问题 How do I get the Scala UTC timestamp in seconds since January 1st, 1970? 回答1: Same way as you would in Java: val timestamp: Long = System.currentTimeMillis / 1000 回答2: As of Java 8 it's possible to do so like so: import java.time.Instant unixTimestamp : Long = Instant.now.getEpochSecond Via micha's answer here: https://stackoverflow.com/a/24703573/577199 来源： https://stackoverflow.com/questions/11352037/scala-utc-timestamp-in-seconds-since-january-1st-1970
