It looks like the inability to set the timestamp of a file is something mtp speciffic. ![]() The timestamps of the unpacked files have been restored correctly. I pulled it out of the phone, plugged it in another computer (Ubuntu 14.04) and was able to unpack another tarball without any errors. It turned out that the MicroSD card itself has been formatted using vfat filesystem without any encryption. 1 They provide support for time acquisition, conversion between date formats, and formatted output to strings. Is the problem related to me using encryption? The C date and time functions are a group of functions in the standard library of the C programming language implementing date and time manipulation operations. Is there any mount option or other magic that will allow setting the files' timestamps on a mounted mtp filesystem? I normally wouldn't worry about it but there are files under Android/data that belong to applications that might be timestamp sensitive. The utimes () function sets the access and modification times of the file pointed to by the path argument to the value of the times argument. This is confirmed by ls -l - it shows the current date and time. Telling me that tar is unable to restore the original timestamp of the files. Tar: 00001.vcf: Cannot utime: Operation not supported The files got restored but for each one I got an error message like: 00001.vcf The function is included via . conftest.c:491:23: error: implicit declaration of function utime is > invalid in C99 -Werror,-Wimplicit-function.Similarly, it also retrieves GMT using gmtime function and converts it to the string format using asctime function. The above example retrieves the current time using the time function and then converts it into a string format to display it. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times. The current UTC date and time is: Fri Mar 22 03:51:20 2019. You can pass data, known as parameters, into a function. It reports the time down to microsecond level. A function is a block of code which only runs when it is called. If the tvnsec field of one of the timespec structures has the special value UTIMENOW, then the corresponding file timestamp is set to the current time. ![]() Does it have any header file to include to produce time in milli seconds. Then replaced the card, formatted the new one and tried to restore my files: hi all, I want to take current time with milli seconds in C. I replaced the MicroSD card in my mobile (Samsung Galaxy S4 Mini running CyanogenMod 11 with encryption) with a bigger one.Ä«efore I pulled the old one out I backed up its content into a tar file:
