LDAP Timestamp Converter

Convert Active Directory and Windows NT timestamps to human-readable dates

What is an LDAP Timestamp?

LDAP timestamps, also called Windows NT Time, Active Directory timestamps, or FILETIME, count the number of 100-nanosecond intervals since January 1, 1601 UTC. They are 18-digit integers used throughout Microsoft's Active Directory, Exchange Server, and Windows file system metadata.

Where You'll Encounter LDAP Timestamps

Active Directory stores account expiration dates (accountExpires), password last-set times (pwdLastSet), and last-logon timestamps (lastLogonTimestamp) in this format. Exchange Server uses them for message delivery times. Windows NTFS file system metadata (creation, modification, access times) also uses this format internally.

How to Convert

Paste any 18-digit LDAP timestamp into the converter above. Chronoshift auto-detects the format and shows you the human-readable date, Unix epoch equivalents, and ISO 8601 format — all with one-click copy buttons.
