How can I solve this error called "Java exception occurred"?

Hello,

I received this error-message while trying to run a script on a cluster:

Error using batch (line 185) Java exception occurred: java.lang.IllegalArgumentException: Negative time

at java.io.File.setLastModified(Unknown Source)

at org.apache.commons.io.FileUtils.doCopyDirectory(FileUtils.java:1435)

at org.apache.commons.io.FileUtils.copyDirectory(FileUtils.java:1230)

Can anybody help me with this? Batch.m is an official script from the Mathworks Company, so its function should be clear.

Thank you in advance :)

Although Batch.m might be an official file from TMW, it can be impeded by user defined function, if they are stored in folders on top of Matlab's PATH.
