theTime = str(theTime)
date_split = theTime.strip().split(' ')
date_today = date_split[0].replace('-', '_')
date_clock = date_split[-1]
date_clock = date_clock.strip().split('.')[0]
date_clock = date_clock.replace(':', '_')
date_show = date_today + '-' + date_clock
print(date_show)
out_path = "./" + date_show
