JSP source code

 

<%
// Obtain the system time
// String ddate = new simpledateformat ("yyyy-mm-dd hh: mm: SS"). Format (calendar. getinstance (). gettime ());
Timezone TZ = timezone. gettimezone ("ETC/GMT-8 ");
Timezone. setdefault (Tz );
Java. util. Date = new java. util. Date (); // obtain the system time.
String nowtime = new simpledateformat ("yyyy-mm-dd hh: mm: SS"). Format (date); // convert the time format to a format that meets the timestamp requirements.
// Timestamp goodsc_date = timestamp. valueof (nowtime); // converts the time

%>

 

Run the following command in Windows:

 

But the webpage is uploaded to Linux: there is a problem with centos5.3.

Eight hours later,

Use the following code:

 

<%
// Obtain the system time
// String ddate = new simpledateformat ("yyyy-mm-dd hh: mm: SS"). Format (calendar. getinstance (). gettime ());
// Timezone TZ = timezone. gettimezone ("ETC/GMT-8 ");
Timezone TZ = timezone. gettimezone ("Asia/Shanghai ");

Timezone. setdefault (Tz );
Java. util. Date = new java. util. Date (); // obtain the system time.
String nowtime = new simpledateformat ("yyyy-mm-dd hh: mm: SS"). Format (date); // convert the time format to a format that meets the timestamp requirements.
// Timestamp goodsc_date = timestamp. valueof (nowtime); // converts the time

%>

 

It is normal.

If it is found that it is not the etc but the etc, the code is corrected:

<%
// Obtain the system time
// String ddate = new simpledateformat ("yyyy-mm-dd hh: mm: SS"). Format (calendar. getinstance (). gettime ());
Timezone TZ = timezone. gettimezone ("ETC/GMT-8 ");
// Timezone TZ = timezone. gettimezone ("Asia/Shanghai ");

Timezone. setdefault (Tz );
Java. util. Date = new java. util. Date (); // obtain the system time.
String nowtime = new simpledateformat ("yyyy-mm-dd hh: mm: SS"). Format (date); // convert the time format to a format that meets the timestamp requirements.
// Timestamp goodsc_date = timestamp. valueof (nowtime); // converts the time

%>

This is OK.

 

Feel it.
