Quietly looking at a new tree and schema to replace our overly complex setup...

We store Date Of Birth in the directory, currently as a stupid Case Ignore String, but I wanted to utilise the attribute syntaxes better to maintain the data. Obviously I can't use Time/Timestamp as people are born before 1970 and, according to the eDir doco:

Used by attributes represented as 64-bit integer values. Integer 64 attributes support the Microsoft Large Integer Syntax and can be used to store large-integer values or dates previous to 1970 or beyond 2038.
What I want to know, has anyone messed around with the ECMA to convert to/from Date and Integer 64? I see the iManager plug-ins do this nicely, just need a clear set of calls to convert.
