The world could be 72 hours away from a historic global agreement on climate change.
Or 100 hours, India warns, depending on the collective wisdom of the parties.
It's nearing the crucial final days at the United Nations climate change conference in Paris, with countries expected to reach a compromise by Friday.
With the 100-hour warning, India hinted parties may have to stay back past the knock off time.
Australia is understood to be showing a fair chunk of its hand in a tactical move to put pressure on the negotiating block of developing nations called the G77 plus China.
By openly pushing for an ambitious agreement, Australia could pressure several nations - like vulnerable developing countries - which also want a strong outcome.
It comes after some in the G77, like Saudi Arabia, employed delay tactics to frustrate talks.
After two days of high-level talks on the latest draft text there are still key issues obstructing consensus.
Negotiators are tired, with some sticking it out the entire night on Monday.
One of the key hurdles is climate finance, with India still keen to have a dig at developed nations for not taking a visible lead.
"We remain disappointed by the low level of climate ambition and support provided by developed countries," Indian Minister of State for Environment Prakash Javadekar said on Tuesday.
"The haves will provide the haves-not."
That's been India's position, with the nation questioning whether rich countries are serious about a $100 billion per year climate finance pledge by 2020.
Developed nations, including Australia, say they are and point to an OECD report that showed finance in 2014 would hit $62 billion.
China, India and other large developing nations dispute the methodology of the report.
The French took over the negotiating process at the weekend, assigning multiple ministers to co-facilitator roles on separate issues.
At a progress update on Tuesday night, facilitators said there was still no clear landing ground on loss and damage finance - something fought for by vulnerable nations, like the Pacific.
Rich nations are wary of loss and damage as it could imply liability.
However, there has been some compromise with facilitators reporting most countries supported the inclusion of an aspirational reference to limiting global warming to 1.5 degrees.
The official goal is expected to be 'two degrees' or, as Australia would like, 'well below two'.
Foreign Minister Julie Bishop is heading Australia's negotiations, while attending side events and bilateral meetings.
She bumped into her Marshall Islands counterpart Tony de Brum on Tuesday, with the pair snapped mid-embrace.
Mr de Brum earlier told media he wanted to confront Ms Bishop over her parliamentary accusation one of his nation's islands hadn't sunk.
Her mistake stemmed from the incorrect island detailed in a transcript by Labor's Tanya Plibersek.
Negotiators will be handed a new, streamlined text on Wednesday in order to scrap more options and produce the final document 196 parties will walk away happy with - whichever day that might be.
