# 高精度计时器 by FantasyDR

# 该类已经被定义为全局变量 $sys_timer
# 如果只需要精确到毫秒，请设置初始化参数为true
# decimal属性设置返回时间值的小数位数。
# ------------------------------------------------------------------------
# 下面是一些有用的方法列表，调用时写：$sys_timer.方法名
# 例如 $sys_timer.clear()
# ------------------------------------------------------------------------
# clear() ：计时器清零
# now() ：获取当前经过的时间，单位毫秒
# now_s() ：获取当前经过的时间，单位秒
