how do i get GMT values from this?

[deadcoder0904]

for example, my timezone asia/kolkata has a gmt +5:30. i was wondering how do i get the gmt value as it is useful while displaying?

think i've got it.

const timezones = getTimeZones()

const options = timezones.map(({ name, currentTimeFormat }) => {
    const label = `(GMT${currentTimeFormat.substring(0, 6)}) ${name.replace(/_/g, ' ')}`
    return { label, value: name }
})
