Sometimes you need to get to the current time zone in the projectTen - :notoginseng: + 0800+800 means the current time zone is the East eight zone.My idea is: Pick a point in time, which is 0 points in Greenwich, then the current number of hours in a global location is the number of time zones for that location. If the current time is greater than 12 points, it proves that the location is west of Greenwich.The code is as follows:#include #include#includeintTime_zone () {time_t currtime=14200704

However, these skills will be quickly forgotten after the college entrance examination.The advantage is gone, the disadvantage of abstract thinking is still there, and the habit of "form calculation" is still there, so "casually submitIt's not surprising that the order of limits is changed.

Understanding some knowledge about TP-LINK router settings, for TP-LINK router users is very important. In China, the mainstream broadband access modes include ADSL, VDSL, FTTB + LAN Dynamic IP + WEB Authentication, FTTB + LAN static IP + WEB authentication, and wired broadband access. Many access solutions are using the router, but compared with different access methods, the TP-LINK router setting method is not the same, today is to use more compatib

Broadband Access Network is a frequently used access method. So I have studied the development and complementarity of broadband access networks. I would like to share with you here, hoping to help you. In recent years, with the rapid development of broadband Internet technology and broadband access network services, broadband access network users have gradually evolved from a single application of high-speed Internet access to comprehensive applications such as VoIP, IPTV, and visual communicati

during stable operation. Better interconnectivity: The ADSL Transceiver is divided into TPS-TC transmission protocol-related aggregation sub-layer according to the function), PMS-TC physical media-related aggregation sub-layer), PMD physical media-related sub-layer) and MPS-TC management protocol-related aggregation sub-layer, used for network management interface), each sub-layer is encapsulated and defines the message between the sub-layer, to help different manufacturers of devices to achiev

encapsulated and the message between each child layer is defined, which facilitates interoperability between different manufacturers ' devices. More operating modes: Full digital mode Annexi with Adsloverpots (ANNEXA) compatible spectrum and full digital mode Annexb with ADSLOVERISDN (ANNEXJ) compatible spectrum, which can be used to transmit uplink data Services using narrowband voice service frequency bands. More stable operation with better spectrum compatibility and line diagnostics. Huaw

, and can achieve Mbps or higher burst traffic. Epon can offer a variety of economic advantages. Ethernet over VDSL technology: This technology helps people use telephone line resources to expand Ethernet coverage. The VDSL can provide more than 10Mbps speed on the copper twisted-pair line, and can overcome the problems of low selection rate and unstable rate of ADSL technology. Wireless local Area networ

In China, the mainstream broadband access mode has the following several: Adsl,vdsl,fttb+lan dynamic Ip+web certification, Fttb+lan static Ip+web certification, cable broadband Internet access. Many access schemes have adopted a router, but compared to different access methods, the router's setting method is not the same, today to use more compatible with the Tp-link broadband road as an example, in detail on the different broadband mode access to the

upgrading the function of MBMS for the existing PS domain-related network elements, it supports MBMS-specific interface functions (such as Gmb), special channels (such as MICH, MTCH/MCCH/MSCH), special physical layer processes (FACH channel selective merge, PTM and PTP switching) and special business processes (such as subscription ). In terms of terminals, MBMS still inherits the existing 3GPP standards to the maximum extent. While the technologies
