FTP server file date

adyr — Thu, 24 Dec 2015 14:19:31 GMT

Hi,

I'm using MQX with KSDK 1.3 and I have created an FTP server that is saving files to an SD card with MFS. It is working except the date / time of files written to the SD card via FTP are always 1/1/1970 (viewed in the FTP client). I have the RTC running with the correct time so is there a way to integrate it with the MFS / FTP server so the corrected date is written to the file?

Thanks,

Adrian.

Hi Adrian:

I think you can try the IO_IOCTL_SET_DATE_TIME command, this command sets the time and date of an open file.

Please refer to the section 3.8.1.25 of MFS user guide for more details

Daniel

Thanks for the information Daniel.

While looking through the FTP / MFS code to see where I could place this I noticed that MFS already tries to write the date based on _time_get. Then it dawned on me that if I synchronised the systems tick with the real time it should all work. So I have now added the following to my start-up code:

//Synchronise systems clock to real time clock
rtc_datetime_t datetime;
RTC_DRV_GetDatetime( FSL_RTCTIMER1, &datetime );
DATE_STRUCT date;
TIME_STRUCT time;

date.YEAR = datetime.year;
date.MONTH = datetime.month;
date.DAY = datetime.day;
date.HOUR = datetime.hour;
date.SECOND = datetime.second;
date.MILLISEC = 0;
_time_from_date(&date, &time);
_time_set(&time);

I'm not sure if that is the most efficient way but it works and now the date/time of any files I create use the current real time.

Adrian.
