Timestamps?

[Duncan A]

Hi all,

Is it possible to record the computer/system time (hour:minutes:seconds.milliseconds) at each stimulus presentation in addition to time in milliseconds (e.g. RT-time)?

I want to use this to match up E-Prime's output with output from an eyetracker. Because the device starts recording before our E-Prime program runs, using time from the start of the program doesn't allow us to match up timestamps.

I'm still very new to using E-Prime, so I hope this question makes sense.

Thanks,

DA

DA,

Look at the "Time, Time$ (functions)" and "Now (function)" topics in
the E-Basic Help facility. If you use EP2.0.10, then you may also
want to consider using the E-Prime SNTP Realtime Clock facility
(Experiment Object Properties, Timing tab) -- you may have to look at
the Knowledge Base or the New Features Guide for documentation on that.

If it were me, I would find some way to establish communication
directly between the eyetracker system and E-Prime for the purpose of
recording solid synchronization signals. And depending on the
eyetracker system, PST can supply E-Prime "Package Files" for working
directly with the eyetracker, which might simplify a lot of this.

Thanks so much, David! The "Time$" function is exactly what I was looking for.

I do have one more question. I looked through the other time-related topics in E-basic Help, all of them seem to leave milliseconds off of the system time. Is there any way to return the system time with hours, minutes, seconds, and milliseconds?

Thanks in advance,
DA

DA,

AFAIK, no. But I do not work for PST, so you might want to ask PST
Support directly. And then please write back here with their response.

Thanks,
