我需要增加/减少PostgreSQL数据库中的时间。
以下是包含列类型为＆＃34;时区没有时区＆＃34;

select start_time from XXXXX;
"2017-05-15 15:08:54.639"
"2017-05-10 17:30:25.056"
"2017-05-10 17:35:35.418"
"2017-05-11 15:05:40.071"
"2017-05-11 18:11:51.431"
"2017-05-18 11:15:00"
"2017-05-11 15:07:43.534"
"2017-05-11 15:10:15.808"
"2017-05-11 15:15:24.847"

"2017-05-11 16:10:15.808"
