Ability to type the duration expression in the global time dropdown

[srikanthccv]

Is your feature request related to a problem?

The options in the global time range are limited. Often users want other time ranges such as 3 hours, 12 hours, 4 days etc. The only way to achieve this today is to use a custom time range which is very difficult. The user should be able to enter the duration expressions such as 3h, 4d and 1w, which should be interpreted as last 3 hours, last 4 days, and last 1 week respectively.

Part of this is already done (any expression that uses numbers followed by m, h, d, w works). It would be wonderful to support any parsable expression such as 1 week, or 2 days. It's nice to have but not mandatory. Most users should be fine with compact inputs such as 1w, 2d, 4h etc..
