If you create an attribute in iManager using the Time syntax, populate the attribute value, and then search for that value using LDAP, LDAP returns a value different from the value populated by iManager.
iManager and LDAP both natively store date values using the first 31 bits of a 32-bit unsigned integer. However, the two applications interpret the most significant bit (MSB) in the integer differently, with iManager using the MSB to store dates earlier than 1970 and LDAP using the MSB to store dates later than 2038. Therefore, the date range used by iManager is 1903-2038, while the date range used by LDAP is 1970-2106.
