Date manipulation: Difference between revisions

Line 1,904:

Langur currently uses the Go time package. Testing with Go 1.14.1 on Linux, the time package doesn't seem to parse "EST" correctly, and it seems to fail silently. Given these conditions, I use "-05:00" instead of "EST" in the input string.

<syntaxhighlight lang="langur">~~val .input = "March 7 2009 7:30pm -05:00"~~

val ~~.iformat~~ = "~~January~~ 2 ~~2006~~ 3:~~04pm~~ -07:00"

val input = "March 7 2009 7:30pm -05:00"

val ~~.oformat~~ = "January 2 2006 3:04pm ~~MST~~"

val iformat = "January 2 2006 3:04pm -07:00"

val oformat = "January 2 2006 3:04pm MST"

val .d1 = datetime .input, .iformat

val d1 = datetime(input, iformat)

val .d2 = .d1 + dr/~~PT12H~~/

val d2 = d1 + dr/T12h/

val .d3 = datetime .d2, "US/Arizona"

val d3 = datetime(d2, "US/Arizona")

val .d4 = datetime .d2, zls

val d4 = datetime(d2, zls)

val .d5 = datetime .d2, "Z"

val d5 = datetime(d2, "Z")

val .d6 = datetime .d2, "+02:30"

val d6 = datetime(d2, "+02:30")

val .d7 = datetime .d2, "EST"

val d7 = datetime(d2, "EST")
