42. It was, therefore, open for a very short time, shorter than the time for which such offers are ordinarily open (Financial Integrity Group Pty Ltd v Farmer (No 4) at [29]), though made at a late stage in the proceedings when it may be expected that Ms Hillman would be aware of the evidence to be led, it having been required to be given initially by affidavit. That is a relevant factor in determining whether the time limited for acceptance of the offer is reasonable: Mainteck Services Pty Ltd v Stein Heurtey SA [2013] NSWSC 1165 at [10]. In that case, the offer was said to be "open for only seven days" (at [17]) though the offeror did explicitly state that if the offeree still wished to settle, further negotiations were possible, though with re-calculation as to costs. Similarly, in Jones v Trad (No 3) [2013] NSWCA 463 at [47] the same period of seven days was also mentioned unfavourably. See also Baulderstone Hornibrook Engineering Pty Ltd v Gordian Runoff Ltd [2006] NSWSC 583 at [38] where five days was regarded as too short a period of time and Ng v Chong [2005] NSWSC 385 at [14] where the offer, made after commencement of the trial, was only open for seven days. Indeed, in Walsh v Walsh (No 2) at [20], the Court considered that an offer open for only ten days (described at [71] as a "relatively short period") might in some circumstances be relevant to whether the offer was unreasonably rejected.
