问题 var Result1 = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local) var Result2 = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.FindSystemTimeZoneById(TimeZoneInfo.Local.Id)); Both this convert Utc time to local time, is there any difference between this 2 different ways in result or performance? which is good? why Microsoft not using TimeZoneInfo.Local directly(as for Result1) in sample here 回答1: The only difference is that the second takes a detour by getting

问题 When using the EWS GetUserAvailability() function, I get in the AttendeesAvailability[i] object a WorkingHours object containing a Start, an End, the WeekDays, and a TimeZoneInfo object. For me, the TimeZoneInfo object always has the name Custom Timezone and a GUID as ID, so I cannot restore the very same time zone using FindSystemTimeZoneById . The time zone that the user can select for his availability, however, is one of the system time zones, so I really expected to find a system time

问题 I'm currently working with different time zones, using java.util.TimeZone . First thing I did was to get a list of TimeZone IDs, using TimeZone.getAvailableIDs(); It returned a bunch of Etc/GMT IDs, such as Etc/GMT Etc/GMT+0 Etc/GMT+1 The Javadoc for TimeZone says to use "For example, GMT+10 and GMT+0010 " To make sure I was using the correct one, I made a small test with both IDs, and the results didn't match what I was expecting: String id = "GMT-1"; Calendar c = Calendar.getInstance

问题 I have a pandas dataframe with UNIX timestamps (these are integers and not time objects). The observations occur in multiple geographic locations, and therefore multiple timezones. I'd like to convert the UNIX timestamp into local time (in a new column) for each of these timezones, based on the geography of the observation (this information is in a column of the dataframe). Simple working example: Creating the dataframe: c1=[1546555701, 1546378818, 1546574677, 1546399159, 1546572278] c2=[

问题 I have a date 2018-06-19 09:06:29 . It is how it is stored in the database. I am using moment-timezone and calling this function. function getDateString(t, tz) { return moment() .tz("America/Chicago") .format('l'); } Here I know that my timezone is "America/Chicago" and it is "UTC-5 hours". I should get the time 5 hours before the time that I have passed as an argument. This function was working perfectly until I upgraded my react. Can anyone know what might be the issue? These are my current

问题 This question already has answers here : How to ISO 8601 format a Date with Timezone Offset in JavaScript? (11 answers) Closed 5 years ago . Why does this method use UTC timezone ( Z ) and not include the local time offset ( +/-HH:SS ) instead? The "ISO" in the method name refers to ISO 8601—which allows for "time zone designations" to be expressed as part of its format. In other words, new Date() tells me both the date and time, and the timezone offset (via getTimezoneOffset() ). But
