-    MSDN description about FILETIME structure:
-
-    The FILETIME structure is a 64-bit value representing the number of 100-nanosecond intervals
-    since January 1, 1601 (UTC).
-
-    The DeltaToEpochInMsec can be calculated like this:
-
-    \code
-        quint64 delta = quint64(QDateTime(QDate(1601, 1, 1)).msecsTo(QDateTime(QDate(1970, 1, 1))))
-            * 10000ULL;
-    \endcode
-
-    But since the value is static, we use a precalculated number here.

-        MSDN suggests to implement the function like this:
-
-        1. Call SystemTimeToFileTime to copy the system time to a FILETIME structure. Call
-           GetSystemTime to get the current system time to pass to SystemTimeToFileTime.
-        2. Copy the contents of the FILETIME structure to a ULARGE_INTEGER structure.
-        3. Initialize a SYSTEMTIME structure with the date and time of the first second of
-           January 1, 1970.
-        4. Call SystemTimeToFileTime, passing the SYSTEMTIME structure initialized in Step 3
-           to the call.
-        5. Copy the contents of the FILETIME structure returned by SystemTimeToFileTime in Step 4
-           to a second ULARGE_INTEGER. The copied value should be less than or equal to the value
-           copied in Step 2.
-        6. Subtract the 64-bit value in the ULARGE_INTEGER structure initialized in Step 5
-           (January 1, 1970) from the 64-bit value of the ULARGE_INTEGER structure initialized
-           in Step 2 (the current system time). This produces a value in 100-nanosecond intervals
-           since January 1, 1970. To convert this value to seconds, divide by 10,000,000.
-
-            We can omit step 1 and 2, cause we get the LARGE_INTEGER passed as function argument.
