LDAP, Active Directory & Filetime Timestamp Converter
There are at least 2 types of LDAP timestamps, an 18 digit timestamp and a timestamp that is based on a Year-Month-Day-format.
Convert 18-digit LDAP/FILETIME timestamps to human-readable date
The 18-digit Active Directory timestamps, also named 'Windows NT time format', 'Win32 FILETIME or SYSTEMTIME' or NTFS file time. These are used in Microsoft Active Directory for pwdLastSet, accountExpires, LastLogon, LastLogonTimestamp, and LastPwdSet. The timestamp is the number of 100-nanosecond intervals (1 nanosecond = one billionth of a second) since Jan 1, 1601 UTC.
The current LDAP/Win32 FILETIME is 132159469710000000 or in scientific notation 13215946971e7
Enter number in full or in scientific/exponential notation:
Milliseconds are discarded (last 7 digits of the LDAP timestamp)

In Windows (command line) use:
w32tm.exe /ntte 131001091660000000
Convert YMD LDAP timestamps
These LDAP timestamps are much more simple and start with the year. The timestamp has the following format: YYYYMMDDHHMMSST. T is the time zone which is usually 'Z' (Zulu Time Zone = UTC/GMT). The tool below can only handle Zulu timestamps.
The current YMD timestamp is 20191019082251Z
