+ OSC_timeTag.h: library for manipulating OSC time tags
+ Matt Wright, 5/29/97
+
+ Time tags in OSC have the same format as in NTP: 64 bit fixed point, with the
+ top 32 bits giving number of seconds sinve midnight 1/1/1900 and the bottom
+ 32 bits giving fractional parts of a second.  We represent this by an 8-byte
+ unsigned long if possible, or else a struct. 
+
+ NB: On many architectures with 8-byte ints, it's illegal (like maybe a bus error)
+ to dereference a pointer to an 8 byte int that's not 8-byte aligned.
