<h3><br>1、获取秒级时间戳与毫秒级时间戳、微秒级时间戳</h3>
<div class="cnblogs_code">
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><img src="https://common.cnblogs.com/images/copycode.gif"></span></div>
<pre>import time
import datetime
t = time.time()
print (t) #原始时间数据
print (int(t)) #秒级时间戳
print (int(round(t * 1000))) #毫秒级时间戳
print (int(round(t * 1000000))) #微秒级时间戳</pre>
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><img src="https://common.cnblogs.com/images/copycode.gif"></span></div>
</div>
<p>返回</p>
<div class="cnblogs_code">
<pre>1499825149.257892 #原始时间数据
1499825149 #秒级时间戳，10位
1499825149257 #毫秒级时间戳，13位
1499825149257892 #微秒级时间戳，16位</pre>
</div>
<p> </p>
<h3>2、获取当前日期时间</h3>
<div class="cnblogs_code">
<pre>dt = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
dt_ms = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f') # 含微秒的日期时间，来源 比特量化
print(dt)
print(dt_ms)</pre>
</div>
<p>返回</p>
<div class="cnblogs_code">
<pre>2018-09-06 21:54:46
2018-09-06 21:54:46.205213</pre>
</div>
<p> </p>
<h3>3、将日期转为秒级时间戳</h3>
<div class="cnblogs_code">
<pre>dt = '2018-01-01 10:40:30'
ts = int(time.mktime(time.strptime(dt, "%Y-%m-%d %H:%M:%S")))
print (ts)</pre>
</div>
<p>返回</p>
<div class="cnblogs_code">
<pre>1514774430</pre>
</div>
<p> </p>
<h3>4、将秒级时间戳转为日期</h3>
<div class="cnblogs_code">
<pre>ts = 1515774430
dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts))
print(dt)</pre>
</div>
<p>返回</p>
<div class="cnblogs_code">
<pre>2018-01-13 00:27:10</pre>
</div>
<p> </p>
<h3>5、时间格式转成另一种时间格式</h3>
<div class="cnblogs_code">
<pre>dt = '08/02/2019 01:00'
dt_new = datetime.datetime.strptime(dt, '%m/%d/%Y %H:%M').strftime('%Y-%m-%d %H:%M:%S')
print(dt_new)</pre>
</div>
<p>返回</p>
<div class="cnblogs_code">
<pre>2019-08-02 01:00:00</pre>
</div>
<p> </p>
<h3>6、转结构体时间struct_time</h3>
<div class="cnblogs_code">
<pre>ta_dt = time.strptime("2018-09-06 21:54:46", '%Y-%m-%d %H:%M:%S')#日期时间转结构体
ta_ms = time.localtime(1486188476) #时间戳转结构体，注意时间戳要求为int，来源 比特量化
print(ta_dt)
print(ta_ms)</pre>
</div>
<p>返回</p>
<div class="cnblogs_code">
<pre>time.struct_time(tm_year=2018, tm_mon=9, tm_mday=6, tm_hour=21, tm_min=54, tm_sec=46, tm_wday=3, tm_yday=249, tm_isdst=-1)
time.struct_time(tm_year=2017, tm_mon=2, tm_mday=4, tm_hour=14, tm_min=7, tm_sec=56, tm_wday=5, tm_yday=35, tm_isdst=0)</pre>
