Description

Hi,

I polled AT+CCLK? once per second for a day. I got the correct result almost every time but once I got totally wrong date:

May 25 17:15:52 ginger Misc1<AT+CCLK?\r
May 25 17:15:52 ginger Misc1>\r\n+CCLK: "9/5/25,14:16:3"\r\n\r\nOK\r\n
May 25 17:15:52 ginger Misc1:AT+CCLK?=>['+CCLK: "9/5/25,14:16:3"', 'OK']
May 25 17:15:53 ginger Misc1<AT+CCLK?\r
May 25 17:15:53 ginger Misc1>\r\n+CCLK: "180/228/0,0:0:2"\r\n
May 25 17:15:53 ginger Misc1:AT+CCLK?=>['+CCLK: "180/228/0,0:0:2"', 'OK']

This does not look like serial port data corruption. Is someting inside calypso not corrupting some memory used to format the reply?
