It helps us easily understand how time zone difference works, and possibly get an idea about the current time in a selected time zone. Point is that no matter if I put the clock back, UTC time will always be right and the string to calculate time since or until current UTC time is always in UTC. This is the list of utc time zone offsets in HH:MM time format and the time difference between universal time. Or is it just the output that's wrong? Instead, maybe use the "timeSinceDate" methods to do the calculations? If I reset my clock -2 hours, the UTC timestamp is also -2 hours, which it shouldn't - reason why I'm using UTC as a reference. And also, UTC time from the method is almost always wrong - lots of reference to other posts here. So, why does the strings I input get converted to the wrong timezone - even though they're set as UTC.
Great Britain/United Kingdom is one hour ahead of UTC during summer. UTC is Coordinated Universal Time, GMT is Greenwich Mean Time. Therefor I need to compare it to an actual UTC date time. Adjusted for Daylight Saving Time (188 places). I am doing a calculation off time difference and since I know that the string that gets sent to these methods are absolutely in "UTC" mode. I also have this method for getting the current time in UTC and convert the string to UTC: + (NSDate*) stringToDateInUtc:(NSString*)str Same thing with a UTC date: in UTC Now: ) So the Epoch is Unix time 0 (1-1-1970) but it is also used as Unix Time or Unix Timestamp. It can be a number of seconds between particular date time and that have passed since 1 January 1970 at Coordinated Universal Time (UTC). (UTC/GMT) Time Zone Converter If you have a web cast, online chat, conference call or other live event where people from all over the world want to attend, this (UTC/GMT) time zone difference converter lets you offer everyone an easy way to determine their own local time and date for your live event in (UTC/GMT). timet local utc - timezone + ( daylight3600:0 ) timezone is the number of seconds away from utc for the current timezone and daylight is 1 to indicate daylight savings time is in play and zero for not. Best time for a conference call or a meeting is between 6:30am-8:30am in ET which corresponds to 7:30pm-9:30pm in Manila.
5:30 pm in EDT is 5:30 am in Manila, Philippines and is 9:30 pm in UTC.
I have a string, that I know will be reference to an UTC timestamp when converting it to an actual NSDate it returns this when printed out: [TimeHelper 18:00:00 +0000 The Unix Timestamp or Unix Epoch Time or POSIX Time is a technique to indicate about a point in time. timet utc mktime ( &date ) then convert it to local time. Eastern Daylight Time is 12 hours behind PST () and 4 hours behind Universal Time Coordinated.
