[haskell-art] hsc timing

[Rohan Drape]

hi alex,

apologies slow reply, the below applies to current darcs version.

http://slavepianos.org/rd/sw/hosc/Sound/OpenSoundControl/Time.hs
http://slavepianos.org/rd/sw/hosc/Sound/OpenSoundControl/OSC.hs

to read the current real valued utc time use 'utcr'.

to construct a time stamp from a real valued utc time use 'UTCr'.

to construct a time stamped osc message use 'Bundle'.

to send the message use 'send'.

to account for haskell runtime jitter and network latency forward
timestamp all messages by whatever 'offset' is required.

ie. along the lines of:

 t <- utcr
 let offset = 0.1
     mkt n = UTCr (n + offset)
     b = Bundle (mkt t) [s_new "test" 1 AddToTail (-1) []]
 send fd b

for notes on changes since hosc-0.4 see:

http://lists.lurk.org/pipermail/haskell-art/2008-June/000137.html

perhaps see also the 'pause' and 'pauseUntil' functions.

kind regards,
rohan
