Convert a String Time to/from a Numeric Time

In various places in ERDDAP, a point in time can be represented as either: This web page has converters that can change string time values (with various formats) to/from numeric time values (with various units strings). It also has converters to change time strings and units strings that use other formats into the formats used by ERDDAP.

To avoid time zone and daylight savings confusion, time values in ERDDAP always use the Zulu (UTC, GMT) time zone, denoted by 'Z'. The converters below accept string times with other time zones.

How ERDDAP Deals with Time


Want To Do Time Conversions from within a Computer Program, Script, or Web Page?

If you change the extension of this web page's URL from .html to .txt, ERDDAP will respond with just the text result.

Percent Encoding - The parameter values in the URL (the parts after '=' signs) must be properly percent encoded (external link): all characters other than A-Za-z0-9_-!.~'()* must be encoded as %HH, where HH is the 2 digit hexadecimal value of the character, for example, a space becomes %20. Characters above #127 must be converted to UTF-8 bytes, then each UTF-8 byte must be percent encoded (ask a programmer for help). There are web sites that percent encode and decode for you (external link).
