According to the Genesis text, there was no way to "indicate seasons and days and years" until Day 4. Hence it is wrong to argue any specific length of time for Days 1-3 from the text. It is wrong to argue that they were instantaneous, it is wrong to argue that they were 24 hours, it is wrong to argue that they were millions of years. The text leaves them indeterminate.
I think that you are exaggerating here.
Genesis 1:5 pretty clearly indicates that the day/night cycle was in place and that there were mornings and evenings. There seems to be no need of further markers to note the alternation of light and darkness or any reason to think that the time periods were any different than from now. The markers may provide more precision, but they do not change the actual time periods.
By my understanding, to the Jews, moonrise denotes the start of the new day. Thus without the moon there is no way to know precisely when the next day starts. Likewise, the use of sundials was known, which represents a method of time-telling which would be impossible if there were merely a sunless alternation of light and dark (and even without a sundial the position of the sun in the sky is of use here).
Thus it seems far more likely to me that Genesis 1:14 simply refers to markers to better enable measurement of time, rather than any fundamental change in the time period of a day. The day/night alternation is set up well before then and there is nothing to suggest any actual change in that period at all - certainly not from millions of years down to twenty-four hours !
