I have long been wondering what it is with Zodiac and the concept of TIME ?

It started out already concerning the CJB murder:

In Zodiac’s November 29, 1966 Confession letter he wrote
(note Zodiac wrote and sent this letter so that it would be received at the exact 1 month anniversary of CJB murder,
Zodiac’s possible obsession with anniversaries (several in the Zodiac case) is another ting that point to some kind of obsession with TIME):

…"WHEN WE WERE AWAY FROM THE LIBRARY WALKING, I SAID IT WAS ABOUT TIME.
SHE ASKED ME "ABOUT TIME FOR WHAT".
I SAID IT WAS ABOUT TIME FOR HER TO DIE…

And in the December 1966 desktop poem:

…"life draining into an
uncertain death.
she won’t (smudge)
die.
this time
someone ll find her.
just wait till
next time."

Concerning daylight Saving Time:
This is a post I posted over at Zodiackiller.com jan 12th 2009:

It show that the date of the Cheri Jo Bates murder was committed on 1966 DST ending,
and the "BATES HAD TO DIE" triple letters were sent on 1967 DST start.
I found this rather interesting:

Cheri Joe Bates murder date: Oct 30, 1966 …Daylight Saving Time ends

The Bates had to die letter sent : Apr 30, 1967 …Daylight Saving Time starts

History of US Daylight Saving Time
Standard time in time zones was instituted in the United States by the railroads in 1883 but it was not officially established until 1918 when the Standard Time Act, which also recognized daylight saving time, was introduced. Daylight saving time was abolished in 1919 due to its unpopularity but returned during World War II in 1942. After the war, many states used their own versions of daylight saving time. According to the U.S. Naval Observatory, the Uniform Time Act of 1966 was introduced to provide standardized daylight saving dates throughout the country. Daylight saving time began on the last Sunday in April and ended on the last Sunday in October. The Act allowed for local exemptions from its observance.

Here is som info on thise two dates in regards to occultism:

(CB was killed the evening before Halloween)
October 31 — Samhain, also known as Halloween, or All Hallows Eve. This date is the Illuminati’s highest day of human sacrifice

April 30 – May 1 — Beltaine Festival, also called Walpurgis Night. This is the highest day on the Druidic Witch’s Calendar. May 1 is the Illuminati’s second most sacred holiday. Human sacrifice is required

Not sure what this all means, if anything, but it sure seems like Zodiac had som significant thing going on concerning "TIME"
