Here are examples of web hits for 'point of time' (not including the many by non-native speakers) that in my view still do NOT prove it's a standard phrase, as summarized in my post in the earlier thread.
Group A, as part of a formal definition or explanation, somewhat artificially substituted for a normal word such as 'instant,' 'moment,' or 'period':
Concise OED: time - 2. a point of time as measured in hours and minutes past midnight or noon. ...
time immemorial - a point of time in the distant past beyond recall or knowledge.
Webster's 1913: moment - 1. A minute portion of time; a point of time; an instant; as, at that very moment.
[Note that, contrary to the implication that might have been drawn from jannek's post of links without actual quotes in the earlier thread, these are NOT dictionary entries for the phrase 'point of time' itself.]
Group B, archaic:
The whole life of man is but a point of time (Sir Walter Scott)
... in reality 'tis not the 1746th, but the 1750th year from the birth of Christ, at which remarkable point of time the christian æra is intended to commence... (Gentleman's Magazine, July 1745)
Group C, computer jargon (and/or poor writing):
The following strings all indicate the same point of time
TIME denotes a cetain [sic] point of time. It consists of year, month, day, hour, minute, second, and a unit of time

Group D, science fiction (and/or poor writing):

If we are looking down upon time from a different dimension, we are able to see more than one point of time at once
Group E, coincidental collocations (the real lexical unit is another phrase such as 'end point'):
The sophisticated astronomical culture of the Central American Maya considered this event to be the end and beginning point of time itself.
