Hi,

today (29 February] failed several my NTP servers during first few 
minutes of the day. The reason was wrong date reported by our Trimble 
ACUTIME 2000 - it forgot the leap year:

$GPGGA,004848.0,5006.106,N,01423.494,E,0,08,0.00,00249,M,045,M,,*52
$GPGSV,2,1,8,18,55,087,42,21,42,070,39,26,26,186,40,15,15,057,38*48
$GPGSV,2,2,8,16,49,209,43,08,34,298,41,27,68,298,44,10,54,156,44*44
$GPRMC,004848.0,A,5006.106,N,01423.494,E,000.00,000.0,010316,00.3,E*67
$GPGGA,004856.0,5006.106,N,01423.494,E,0,08,0.00,00249,M,045,M,,*5D
$GPGSV,2,1,8,18,55,087,43,21,42,070,39,26,25,186,40,15,15,057,37*45
$GPGSV,2,2,8,16,49,209,43,08,35,298,41,27,68,298,43,10,54,155,44*41
$GPRMC,004856.0,A,5006.106,N,01423.494,E,000.00,000.0,010316,00.3,E*68

This particular GPS receiver works reliable for 15 years, so three leap 
years already passed without problem. Does anybody else observed similar 
behaviour?

thanks,
