- 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 a 64-bit
- unsigned long if possible, or else a struct.
-
- NB: On many architectures with 64-bit ints, it's illegal (like maybe a bus error)
- to dereference a pointer to a 64-bit int that's not 64-bit aligned.
