As discussed in connection of the musl update PR ( starting from 
https://github.com/openwrt/openwrt/pull/3004#issuecomment-764479005 ), the 
addition of "-u" to the hwclock options seems to fix the strange timestamps 
in early boot system logs that I noticed earlier.

I think that in the current form the busybox update to 1.33.0 works ok. I 
have been using it in my own builds since early January for ath79/WNDR3700, 
ipq806x/R7800 and mvebu/WRT3200ACM.

Would be great to have it in the tree before the 21.0x branching.


PS. this patch series is already actually v4, as patch v3 was sent on 7 Jan 2021.
