setTime()
Sets a time to the value specified in the argument.
Synopsis
time setTime(time &t, unsigned year, unsigned month, unsigned day [, unsigned hour [, unsigned minute [, unsigned second [, unsigned milli [, bool
daylightsaving]]]]]);
Parameters
| Parameter | Description |
|---|---|
| t | Time to be set |
| year | Year |
| month | Month |
| day | Day |
| hour | Hours |
| minute | Minutes |
| second | Seconds |
| milli | Milliseconds |
| daylightsaving | Summer or winter time |
Return value
Equal to the value of t, in the event of errors 0 [1970.1.1 00:00:00.000000000] (UTC)
Errors
missing/incorrect arguments
Description
The function setTime()sets the time variable t to the value specified in the argument. The default value of the optional arguments hour , minute, second and milli is zero. A minimum series of arguments is therefore "1996, 3, 5" for the 5th March 1996, exactly zero hours. The argument "daylightsaving" specifies whether the time is to be understood as summer or winter time: Values are "TRUE" or "FALSE". Depending on the transferred time (summertime/wintertime), the default is either "TRUE" or "FALSE".
Assure, that the change from daylight saving to local time is either managed by the system or by a radio clock. If both techniques are used, this can cause a double change of time.
Example
main()
{
time t;
setTime(t, 1999,8,17);
}The example below sets the time to null time = 1.1.1970.
main(mapping event)
{
time nullTime;
setTime(nullTime, year((time)0), month((time)0), day((time)0), hour((time)0), minute((time)0), second((time)0));
DebugN("Time:", nullTime);
}The example outputs the UTC time: WCCOAui1:["Time:"][1970.01.01 00:00:00.000000000]
Under some operating systems such as CentOS a date before 1970 exists.
