T2 Dependant转永居的申请时间疑问

大家好，我现在的dependant签证今年7月14日到期。我是2013年8月15日入境的，当时的签证有效期是6月28日。我比签证日期晚入境。

因为之前看到gov上写，晚入境的话，有效期起始日期和实际入境日期之间的时间算入合理absence时间，所以我就以为，按比说明，申请永居的时间应该是按签证日期计算的。但是，今天又在gov的申请表指南里看到以下内容:

5. When to apply
   You and any dependants applying with you should apply before the end of your/their permitted stay in the UK.

For most categories covered by this form, you must complete a qualifying period in the UK before you
can qualify for settlement. If you entered the UK with a visa several weeks or more after the date from
which it was valid for use, you may need to apply for an extension of stay to complete the relevant
qualifying period.

Please do not apply more than 28 days before completing the qualifying period. If you apply earlier
than that, your application may be refused. If that happens, we will not refund the fee and you will
have to pay again when reapplying.

所以，我还是要续签dependant后才能再申请永居吗？我就差4天啊！！好悲催。。。

谢谢大家！希望有类似情况已经拿下永居的亲给予明确指点！感谢！

我还是觉得你不用续签，2018年1月11日的T2以及T2depandent永居pdf说明里面还是写可以把签发日期到入境日期之间算入到180天离境时间里面。

Period between the issue of entry clearance and entering the UK
The period between entry clearance being issued and the applicant entering the UK may be counted toward the qualifying period. Any absences between the date of issue and entry to the UK are considered an allowable absence. This period will count towards the 180 days allowable absence in the continuous 12 month period. The applicant does not need to provide evidence to demonstrate the reason for delayed entry.
If the delay is more than 180 days, you can only include time after the applicant entered the UK in the continuous period calculation.
你看到的那段话可以适用于别的签证，比如T1。
我等你申请的消息啊，因为我也是这个情况，但是我比你晚申请

亲，加你微信啦！

然后，我帖子里发的那段话，several weeks这个说法真的很confused，为啥就不能说具体时间呢？不过我有个学法律的朋友帮我看了咱俩发的两段话，最后总结是这个several weeks指的是离境超过180天的时间。虽然我真的不懂她是怎样理解到这个点的，但是毕竟她是学霸，我这个学渣反驳不了的
