Mrs. Cason. The weight of the card causes the clock to stamp the time.
Mr. Hubert. Now, is that clock checked at any time as to accuracy?
Mrs. Cason. I don’t know how often they are checked. I do know that sometimes we find a discrepancy as to the time on the clock insofar as sometimes when we dispatch—when we sent a call sheet through and the time received may be—it says, this could have been 11:23 on the time I received the call, and when we dispatched it it would have shown 11:22, then we would know that the clocks were off, because we couldn’t—I couldn’t receive a call after we had dispatched it.
Mr. Hubert. But, the dispatcher would be using a different clock from you?
Mrs. Cason. And when we find these errors in these clocks this way, someone in the office usually adjusts them to where they all are stamping the same time. It doesn’t happen very often that they get out of time, but sometimes they do.
Mr. Hubert. They are not all tied into a master clock?
Mrs. Cason. No; not as far as I know. I don’t really know how the system works, but I don’t believe they are. I believe they are all on individual basis.
Mr. Hubert. I notice that Exhibit 5135 shows an “M.J.”; is that in your handwriting?
Mrs. Cason. Yes; it is.
Mr. Hubert. Well——
