timeutil

func Lookback ¶ added in v1.5.15

func Lookback(s string) (d time.Duration, ok bool)

Lookback reports the span of a past-relative duration ("24h", "30d") — the form Parse reads as "now minus duration". ok is false for every other form (absolute times, "now", "+" future offsets).

func Parse ¶

func Parse(s string) (int64, error)

Parse converts a time string to a unix timestamp (seconds). Supported formats:

• Go duration (relative to now): "5m", "1h", "24h", "168h" Interpreted as "now minus duration"
• Future duration with "+" prefix: "+24h", "+7d" Interpreted as "now plus duration"
• Day shorthand: "7d", "30d" — converted to hours automatically
• Date: "2026-04-01" (parsed as local midnight)
• Datetime: "2026-04-01 10:00:00" or "2026-04-01T10:00:00" (parsed as local time)
• RFC3339 with timezone: "2026-04-01T10:00:00+08:00" / "...Z" (the format the SDK emits)
• Unix timestamp in seconds: "1712000000" (passed through)
• Unix timestamp in milliseconds: "1712000000000" (divided down to seconds; distinguished from seconds by magnitude — see msThreshold below)
