Time functions

  • Latest Dynatrace
  • Reference

Time functions return the decimal number for a particular time value, calculate the number of time units (days, months, years) between two dates, and allow to determine timestamps and timeframes, among others.

duration

Creates a duration from the given amount and time unit.

Syntax

duration(value, unit)

Parameters

Returns

The data type of the returned value is duration.

Examples

Example 1
data record(value = 1000, unit = "ns"),
     record(value = 60, unit = "s"),
     record(value = 1000 * 60 * 60 * 24, unit = "ms"),
     record(value = 24, unit = "h")
| fieldsAdd duration(value, unit)

Query result:

formatTimestamp

Formats the timestamp according to a format string (using the defined interval).

Timestamps according to the ISO 8601 standard can be parsed and converted to the timestamp datatype.

All letters A to Z and a to z are reserved as pattern letters. Any non-letter characters, other than [, ], {, }, # and the single quote will be output directly. However, it is recommended to use single quotes around all characters that you want to output directly to ensure that future changes do not affect your query. Unrecognized pattern letters result in an error. See Java DateTime Formatter for the list of supported patterns and symbols.

Syntax

formatTimestamp(timestamp [, interval] [, format] [, timezone] [, locale])

Parameters

Returns

The data type of the returned value is string.

Examples

Example 1
data record(timestamp = toTimestamp("2019-08-01T09:30:00.000-0400"))
| fieldsAdd formatted = formatTimestamp(timestamp, format:"MM-dd-yyyy"),
            year      = formatTimestamp(timestamp, format:"y"),
            month     = formatTimestamp(timestamp, format:"M"),
            week      = formatTimestamp(timestamp, format:"w"),
            dayofWeek = formatTimestamp(timestamp, format:"E", locale:"en-US"),
            hour      = formatTimestamp(timestamp, format:"H"),
            time      = formatTimestamp(timestamp, format:"HH:mm, VV"),
            timeET    = formatTimestamp(timestamp, format:"HH:mm, VV", timezone:"US/Eastern")
