How to filter by gv() in JSONPath?

I’m making a widget to view the Splatoon schedule.

The schedule changes every two hours, and there is a nine-hour difference from the time zone in my area.

json source: https://splatoon3.ink/data/schedules.json

gv now

$if(
df(HH%2 = 1,
df(yyyy-MM-dd'T'HH:00:00,r9h)+Z,
df(HH%2 = 0,
df(yyyy-MM-dd'T'HH:00:00,r8h)+Z
)$

text source

$wg(
"https://splatoon3.ink/data/schedules.json", json,
".data.xSchedules.nodes[?(@.startTime == 
'2024-04-12T12:00:00Z')].xMatchSetting.vsStages[0].name")$

I want the code to work even if I write gv(now) for the “2024-04-12T12:00:00Z” place, what should I do?
