Abstract
A network terminal device prevents a timestamp from becoming unnatural accompanying a correction of a local time during a daylight-saving time. During the daylight-saving time, the local time is moved forward by one hour, and the time zone is also moved forward by one hour. When the daylight-saving time ends, both the local time and the time zone are moved backward by one hour.
Claims9
A network terminal device comprising:
- a transmission/reception unit which transmits or receives data using a network protocol;
- a clocking unit which generates a timestamp to be applied to the data transmitted or the data received by the transmission/reception unit, wherein the timestamp includes a local time value and a time zone value;
- and
- a daylight-saving time correcting unit which changes the local time value and the time zone value according to a daylight-saving time at a start of a daylight-saving time period, and returns the local time value and the time zone value, which have been corrected according to the daylight-saving time, to an original value at an end of the daylight-saving time period.
A network terminal device, which uses a network protocol to transmit or received data and generates a timestamp, the network terminal device comprising:
- means for correcting, wherein the timestamp includes a local time value and a time zone vale, the means for correcting moves forward the local time value and the time zone value according to a daylight-saving time during a daylight-saving time period, and moves backward the local time value and the time zone value, which have been corrected according to the daylight-saving time, to an original value at an end of the daylight-saving time period.
A timestamp correcting method of a network terminal device, which uses a network protocol to transmit or receive data and generates a timestamp, the timestamp correcting method comprising the steps of;
- moving forward a local time value and a time zone value according to a daylight-saving time during a daylight-saving time period, and moving backward the local time value and the time zone value, which have been corrected according to the daylight-saving time, to an original value at an end of the daylight-saving time period, wherein the timestamp includes the local time value and the time zone value.
