Welcome.
Here's the SGGS quote on it:
What was that time, and what was that moment? What was that day, and what was that date?
What was that season, and what was that month, when the Universe was created?
The Pandits (the religious scholars) cannot find that time, even if it is written in the Puraanas.
That time is not known to the Qazis (who study the Koran).
The day and the date are not known to the Yogis, nor is the month or the season.
The Creator who created this creation, only He Himself knows.
Bearing in mind it's a poem in Gurmukhī (Sikh literary language and name of script), and God is genderless in Sikhism.
