It gets tricky when there are adjacent errors, unless you report the time in the middle twice, one at the end of the first and once at the beginning of the second. You could write a pretty simple sed script to pull all the lines from timestamp N to timestamp N+1 into the buffer, check for error and write to output or side file if any, get rid of all but the last line, and loop back to filling the buffer up to the next time stamp.
It would be easy to make the buffer load into one line before writing it out, so they can be handled more simply after.

LEARN ABOUT PHP
ob_end_clean
OB_END_CLEAN(3) 1 OB_END_CLEAN(3)
ob_end_clean - Clean (erase) the output buffer and turn off output buffering
SYNOPSIS
bool ob_end_clean (void )
DESCRIPTION
This function discards the contents of the topmost output buffer and turns off this output buffering. If you want to further process the
buffer's contents you have to call ob_get_contents(3) before ob_end_clean(3) as the buffer contents are discarded when ob_end_clean(3) is
called.
The output buffer must be started by ob_start(3) with PHP_OUTPUT_HANDLER_CLEANABLE and PHP_OUTPUT_HANDLER_REMOVABLE flags. Otherwise
ob_end_clean(3) will not work.
RETURN VALUES
Returns TRUE on success or FALSE on failure. Reasons for failure are first that you called the function without an active buffer or that
for some reason a buffer could not be deleted (possible for special buffer).
ERRORS
/EXCEPTIONS
If the function fails it generates an E_NOTICE.
EXAMPLES
The following example shows an easy way to get rid of all output buffers:
Example #1
ob_end_clean(3) example
<?php
ob_start();
echo 'Text that won't get displayed.';
ob_end_clean();
?>
SEE ALSO
ob_start(3), ob_get_contents(3), ob_flush(3).
