 Pure Go TAI64N (http://cr.yp.to/libtai/tai64.html) implementation.
 Pure Go TAI64N (http://cr.yp.to/libtai/tai64.html) implementation.

+cmd/tai64nlocal contains similar to DJB's one utility.
+Example TAI64N creation:
+
+    import "go.cypherpunks.ru/tai64n"
+
+    tai := new(tai64n.TAI64N)
+    tai64n.FromTime(time.Now(), tai)
+    println(tai.Encode()) // @400000005fd24ce33323c4d1
