3  * time.h - NTFS time conversion functions.  Part of the Linux-NTFS project.
11 #include <linux/time.h>		/* For current_kernel_time(). */
19  * utc2ntfs - convert Linux UTC time to NTFS time
20  * @ts:		Linux UTC time to convert to NTFS time
22  * Convert the Linux UTC time @ts to its corresponding NTFS time and return
25  * Linux stores time in a struct timespec64 consisting of a time64_t tv_sec
30  * NTFS uses Microsoft's standard time format which is stored in a s64 and is
38 	 * converted to 100ns intervals, and then add the NTFS time offset.  in utc2ntfs()
45  * get_current_ntfs_time - get the current time in little endian NTFS format
47  * Get the current time from the Linux kernel, convert it to its corresponding
48  * NTFS time and return that in little endian format.
59  * ntfs2utc - convert NTFS time to Linux time
60  * @time:	NTFS time (little endian) to convert to Linux UTC
62  * Convert the little endian NTFS time @time to its corresponding Linux UTC
63  * time and return that in cpu format.
