gmmktime() — internals

Where it lives

• Signature: src/builtins/system/gmmktime.rs
• Lowering: src/codegen/lower_inst/builtins/system.rs:151 (lower_gmmktime)
• Function symbol: lower_gmmktime()

Lowering notes

• Lowers gmmktime(...): the UTC counterpart of mktime().
• Identical six-integer argument marshalling, but dispatches to __rt_gmmktime, which
• interprets the broken-down date/time as UTC (timegm) instead of local time.

Runtime helpers

The following runtime helpers are referenced:

• __rt_checkdate
• __rt_getdate
• __rt_gmmktime
