Unix Time

.: Description

This include contains two functions that allow you to convert unix time to normal time and vice versa.

Unix time on wiki: http://en.wikipedia.org/wiki/Unix_time
Timezone info: http://www.epochconverter.com/epoch/timezones.php

.: Commands

UnixToTime - This will convert unix time to normal time.
TimeToUnix - This will convert normal time to unix time.

.: Usage

UnixToTime( iUnixTime , &iYear , &iMonth , &iDay , &iHour , &iMinute , &iSecond , [ TimeZone ] )
- iUnixTime - Unix time value to be converted to normal time.
- iYear .. iSecond - Normal time values passed by-reference.
- [ TimeZone ] - Optional parameter to obtain time values adjusted for a particular timezone. By default, UTC time is returned which has no timezone adjustment (same as what get_systime() returns). You can pass a timezone of your choice or use UT_TIMEZONE_SERVER to use the timezone of the server machine.

TimeToUnix( iYear , iMonth , iDay , iHour , iMinute , iSecond , [ TimeZone ] )
- iYear .. iSecond - Normal time values to be converted to unix time.
- [ TimeZone ] - Optional parameter to obtain time values adjusted for a particular timezone. By default, UTC time is returned which has no timezone adjustment (same as what get_systime() returns). You can pass a timezone of your choice or use UT_TIMEZONE_SERVER to use the timezone of the server machine.

Comments: This include can be useful for working with timestamps or any task involving time\date manipulation. When using a timezone offset, only use it on a UTC (0 offset) time value. Specifying a timezone on a time value that is already offsetted will provide inaccurate results.

.: Example Code

PHP Code:


		
			
public UnixTime()
{
    new iTime , iTimeAdjusted , iYear , iMonth , iDay , iHour , iMinute , iSecond;
    
    iTime = get_systime();
    
    //Display get_systime() value which is UTC time (no +/- adjustment for timezone)
    server_print( "get_systime() = %d" , iTime );
    UnixToTime( iTime , iYear , iMonth , iDay , iHour , iMinute , iSecond );
    server_print( "get_systime() Time = %02d/%02d/%d %02d:%02d:%02d" , iMonth , iDay , iYear , iHour , iMinute , iSecond );
    
    //Display time value adjusted with TimeToUnix()
    iTimeAdjusted = TimeToUnix( iYear , iMonth , iDay , iHour , iMinute , iSecond , UT_TIMEZONE_SERVER );
    UnixToTime( iTimeAdjusted , iYear , iMonth , iDay , iHour , iMinute , iSecond );
    server_print( "TimeToUnix Adjusted Time = %02d/%02d/%d %02d:%02d:%02d" , iMonth , iDay , iYear , iHour , iMinute , iSecond );
    
    //Display time value adjusted with UnixToTime()
    UnixToTime( iTime , iYear , iMonth , iDay , iHour , iMinute , iSecond , UT_TIMEZONE_SERVER );
    server_print( "UnixToTime Adjusted Time = %02d/%02d/%d %02d:%02d:%02d" , iMonth , iDay , iYear , iHour , iMinute , iSecond );
}

.: Changelog

v0.3
- Added optional parameter for specifying a timezone.
v0.2
- Added reset to 0 of hour variable in UnixToTime function. This was only causing an issue if the hour variable was holding a value when passed into UnixToTime (since it is passed by reference). [thx stupok]
v0.1
- Initial release

Re: [INC] Unix Time Conversion

I wrote up a header file for AlliedModders time. I hope you like it.

Good job!

Re: [INC] Unix Time Conversion

HAHA Valve like always is right :mrgreen:

Re: [INC] Unix Time Conversion

haha nice job chief :wink:

Re: [INC] Unix Time Conversion

tyvm for this :mrgreen:, you saved me some work

EDIT:
ARGH >_< I found a bug

I'm going to try to squash it, here are the details:

Code:

        new iYear = 0

        new iMonth = 0

        new iDay = 0

        new iHour = 0

        new iMinute = 0

        new iSecond = 0

        new iUnixTime = 123456789

        

        UnixToTime( iUnixTime, iYear, iMonth, iDay, iHour, iMinute, iSecond )

        

        server_print("UnixToTime:(%i)->(%i.%i.%i %i:%i:%i)", iUnixTime, iYear, iMonth, iDay, iHour, iMinute, iSecond )

        

        iUnixTime = TimeToUnix( iYear, iMonth, iDay, iHour, iMinute, iSecond )

        

        server_print("TimeToUnix:(%i.%i.%i %i:%i:%i)->(%i)", iYear, iMonth, iDay, iHour, iMinute, iSecond, iUnixTime )

        

        iYear++; iMonth++; iDay++; iHour++; iMinute++; iSecond++

        

        iUnixTime = TimeToUnix( iYear, iMonth, iDay, iHour, iMinute, iSecond )

        

        server_print("TimeToUnix:(%i.%i.%i %i:%i:%i)->(%i)", iYear, iMonth, iDay, iHour, iMinute, iSecond, iUnixTime )

        

        UnixToTime( iUnixTime, iYear, iMonth, iDay, iHour, iMinute, iSecond )

        

        server_print("UnixToTime:(%i)->(%i.%i.%i %i:%i:%i)", iUnixTime, iYear, iMonth, iDay, iHour, iMinute, iSecond )

Output:

Code:

UnixToTime:(123456789)->(1973.11.29 21:33:9)

TimeToUnix:(1973.11.29 21:33:9)->(123456789)

TimeToUnix:(1974.12.30 22:34:10)->(157674850)

UnixToTime:(157674850)->(1974.12.30 44:34:10)

Basically, the hours are being incremented instead of being replaced.

The fix:

Add the highlighted line.

Code:

stock UnixToTime( iTimeStamp , &iYear , &iMonth , &iDay , &iHour , &iMinute , &iSecond )
{
    new iTemp;
    
    iYear = 1970;
    iMonth = 1;
    iDay = 1;
    iHour = 0;
//...

Re: [INC] Unix Time Conversion

When I was coding it I was always using a fresh variable passed only once so I never ran into that bug.

Thanks, ~~chief~~ ~~boss~~ ~~buddy~~ champ

I would +k you but I need to spread some out first

Re: [INC] Unix Time Conversion

Bugsy, awesome!!! I like it, Thanks!

Re: [INC] Unix Time Conversion

New revision posted, read description for details.
