将两个字符串都转换为时间戳(以您选择的分辨率为单位,例如毫秒,秒,小时,天,等等),从后一个减去前一个,将您的随机数(假设分布在中range [0, 1])乘以该差,然后再次加到较早的一个。将时间戳转换回日期字符串,并且您在该范围内有一个随机时间。
Python示例(输出几乎是您指定的格式,而不是0填充-归咎于美国时间格式约定):
import random
import time
def str_time_prop(start, end, format, prop):
"""Get a time at a proportion of a range of two formatted times.
start and end should be strings specifying times formated in the
given format (strftime-style), giving an interval [start, end].
prop specifies how a proportion of the interval to be taken after
start. The returned time will be in the specified format.
"""
stime = time.mktime(time.strptime(start, format))
etime = time.mktime(time.strptime(end, format))
ptime = stime + prop * (etime - stime)
return time.strftime(format, time.localtime(ptime))
def random_date(start, end, prop):
return str_time_prop(start, end, '%m/%d/%Y %I:%M %p', prop)
print(random_date("1/1/2008 1:30 PM", "1/1/2009 4:50 AM", random.random()))
