hello! 

is there away to get different time stamps for when people start different blocks? in my datafile i only see a single time stamp for each participant. 

thank you so much! 

You can log the given <block> element's timestamp properties or the current time at the start of a given block. Something like

<values>
/ blockstarttime = -1
/ blocktimestamp = -1
</values>


<block a>
/ onblockbegin = [
values.blockstarttime = script.currenttime;
values.blocktimestamp = block.a.timestamp;
]
/ trials = [1-4 = mytrial]
</block>

<block b>
/ onblockbegin = [
values.blockstarttime = script.currenttime;
values.blocktimestamp = block.b.timestamp;
]
/ trials = [1-4 = mytrial]
</block>

<trial mytrial>
/ posttrialpause = 500
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>

<text mytext>
/ items = ("Press SPACE")
</text>

<data>
/ columns = (date time subject group blocknum blockcode values.blockstarttime values.blocktimestamp trialnum trialcode stimulusitem response latency correct)
</data>

thank you!

I am now having a problem where when i'm declaring the data columns (see below), the stimulusnumber/item/onset only appears for the first stimulus and no longer includes stimulusitem2-6 (perhaps also because each block has a different number of stimuli appearing on each trial), however when i separately declare "stimulusitem2, stimulusitem3" etc. in data, it gives warnings and doesn't appear to record that data.
<data>
/ columns = (date time values.blockstarttime values.blocktimestamp group subject blocknum trialnum blockcode trialcode pretrialpause posttrialpause trialduration trialtimeout response latency stimulusnumber stimulusitem stimulusonset)
</data>
thank you for your help!!
