Convert Time Field

Summary

Converts time values stored in a string or numeric field to a date field. The tool can also be used to convert time values stored in string, numeric, or date fields into custom formats such as day of the week and month of the year.

Usage

  • If the input time field selected is a string or text field, the input time format can be selected from a list of supported time field formats, or you can define a custom time field format to interpret custom date or time values in the string field. For more information about custom formats for string fields, see converting string time values into date format.

  • If the input time field selected is numeric (short, long, float, or double), the input time format can be selected from a list of supported standard time field formats. Custom time formats are not supported with numeric fields.

Syntax

ConvertTimeField(in_table, input_time_field, {input_time_format}, output_time_field, {output_time_type}, {output_time_format})
ParameterExplanationData Type
in_table

The layer or table that contains the field containing the time values that need to be converted.

Table View
input_time_field

The field containing the time values. May be of type short, long, float, double, text, or date.

Field
input_time_format
(Optional)

The format in which the time values were stored in the input time field. Either a standard time format can be selected from the drop-down list or a custom format can be entered.

  • If the data type of the time field is date, no time format is required.
  • If the data type of the time field is numeric (Short, Long, Float, or Double), a list of standard numeric time formats is provided in the drop-down list.
  • If the data type of the time field is string, a list of standard string time formats is provided in the drop-down list. For string fields, you can also choose to specify a custom time format. For example, the time values may have been stored in a string field in one of the standard formats such as yyyy/MM/dd HH:mm:ss or in a custom format such as dd/MM/yyyy HH:mm:ss. For the custom format, you can also specify the a.m., p.m. designator. Some commonly used formats are listed below:
    • yyyy - Year represented by four digits.
    • MM - Month as digits with leading zero for single-digit months.
    • MMM - Month as a three-letter abbreviation.
    • dd - Day of month as digits with leading zero for single-digit days.
    • ddd - Day of week as a three-letter abbreviation.
    • hh - Hours with leading zero for single-digit hours; 12-hour clock.
    • HH - Hours with leading zero for single-digit hours; 24-hour clock.
    • mm - Minutes with leading zero for single-digit minutes.
    • ss - Seconds with leading zero for single-digit seconds.
    • t - One character time marker string, such as A or P.
    • tt - Multicharacter time marker string, such as AM or PM.
