Get the Olson TZ name for the local timezone?

阅读更多关于 Get the Olson TZ name for the local timezone?

问题 How do I get the Olson timezone name (such as Australia/Sydney ) corresponding to the value given by C's localtime call? This is the value overridden via TZ , by symlinking /etc/localtime , or setting a TIMEZONE variable in time-related system configuration files. 回答1: I think best bet is to go thru all pytz timezones and check which one matches local timezone, each pytz timezone object contains info about utcoffset and tzname like CDT, EST, same info about local time can be obtained from

Get the current time in C

问题 I want to get the current time of my system. For that I'm using the following code in C: time_t now; struct tm *mytime = localtime(&now); if ( strftime(buffer, sizeof buffer, "%X", mytime) ) { printf("time1 = \"%s\"\n", buffer); } The problem is that this code is giving some random time. Also, the random time is different everytime. I want the current time of my system. 回答1: Copy-pasted from here: /* localtime example */ #include <stdio.h> #include <time.h> int main () { time_t rawtime;

Globally convert UTC DateTimes to user specified local DateTimes

阅读更多关于 Globally convert UTC DateTimes to user specified local DateTimes

问题 I am storing all the DateTime fields as UTC time. When a user requests a web page, I would like to take his preferred local timezone (and not the local timezone of the server machine) and automatically display all the DateTime fields in all the web forms as local dates. Of course, I could apply the conversion on every DateTime.ToString() call in every form or implement some helper utility but it is a time consuming task, and also there are some 3rd party components which are tricky to
