Answer

If you mean the Jain “2nd kaal” as a daily observance time, there is no single universal clock time for it. In Jain practice, the exact timing usually depends on local sunrise, your city, and the temple or sect tradition. JainKnowledge specifically notes that some Jain timings do not have one fixed time and can vary by local practice. ( jainknowledge.com)

Explanation

So, “today” can only be translated into an exact time after knowing your location. In many Jain observances, the morning timing is counted relative to sunrise, so the window shifts from place to place and season to season. ( jainknowledge.com)

Takeaway

If you mean a specific Jain ritual or fast, the exact 2nd kaal is location-based, not one fixed time for everyone.
